Automatic 802.1x Reconnect?

Hello, I'm using my mac on a university network that suffers a poor wireless connection on times, leaving me disconnect for one minute because the "network has been compromised" I am forced to manually wait one minute and reconnect manually in the internet connect application.
I am wondering how I could automate this process so as the mac would reconnect on its own, so that if I am not physically here, the mac will still maintain internet connectivity so as I can connect to it while I am away.
Cheers,
Bayman

I have had some limited success, I am using a crontab (using Cronnix) to run the utility airport -p every minute to connect using the system preferences, now running this command from a terminal works fine in connecting to the network.
However, when it is run from the crontab, it doesn't seem to be using the keychain for the network authentication certificate (keeps asking to accept the certificate whenever it connects) and also asks for the password to connect, all of which is in the keychain and does not need to be inputed when the airport -p command is ran from terminal.
How can I get the crontab to use these keychain credentials?

Feature Request: Scan attached drives to automatically find and reconnect "missing" images

This is the kind of thing that computers are good for. I'm surprised that we've made it all the way to version 5 without this feature being added. It would be relatively easy.
Scan the catalog to make an internal list of all images that are "missing" (the raw file is not found where the catalog says it should be).
Scan the attached hard drives and make an internal list of all images on the system.
Compare the file names, sizes and dates of all of the found images and match them up.
You could provide a UI to confirm the reconnected images, or simply do it automatically. If desired, you could use EXIF data in the images to help confirm that the proper images are being connected. In fact, this step could be used as an "advanced" option to find images where the filename has changed.
Thanks for your consideration!

(an original Raw Shooter and RawShooter/Pro user - which Adobe purchased and turned into Lightroom 1.0 - it's been a wonderful ride so far!)

Eliminating step 2 eliminates the security of an immediate backup. I don't want to ever tell a customer that I lost their images. The backup is done just as soon as possible.
Doing the processing on the SSD while having backed up to storage lets me get through thousands of images on a weekly basis (all things related to weddings as well as family portraits, seniors and the like).
The syncing process is automated (in fact, most of my processes are). It keeps *me* fast and efficient.
So why argue against a tool that can benefit not only me but others that have lost their images (for reasons having nothing to do with me or my workflow)? I am involved in many forums and have frequently helped people to find their lost images. I love that Lightroom easily reconnects the images. The only hard part is finding what happened to them (often they did a bonehead drag and drop of a folder and moved the images somewhere they didn't expect, sometimes they changed drive letters, sometimes they purposely move files and just don't realize the repercussions).
ALL of these people would benefit from adding this feature.
Why try to argue against it? I don't need a solution to my workflow. I love my workflow. I just think this feature would be beneficial to me and lots of other people.
Thanks for understanding.

How to automatically reconnect to a NAS device when wireless drops..

When my mini sits idle for awhile, the wireless network connection drops. I've read (I thought) that this is a "know/common" problem.
My question is, I have a NAS device connected to my network. Everytime the signal drops, I have to reconnect to the device as it doesn't show on my desktop. Is there a way to make the mini reconnect automatically when I reconnect to my wireless signal?
Thanks.

As a client OS X supports the major two VPN protocols, PPTP and L2TP over IPSec. As a server technically OS X supports both of these too but the difference is this sort of thing was more aimed at OS X Server so there is no nice GUI to work with.
Of course I wouldn't have suggested this if there wasn't a nicer solution at hand. I'm sure there are others too but what I know works (as I use it) is [iVPN|http://macserve.org.uk/projects/ivpn>, essentially a GUI wrapper to the already installed daemons. As far as performance goes it's dependent on both your connection at home and the connection wherever you are but then that would also be the case if trying to access the NAS remotely anyway. I'd also guess this will result in a safer connection too as the file sharing protocols you're using probably aren't concerned about encryption.
The only thing I'd say is I do believe there are issues if both the home network and the place you are at are both using the same private IP range, assuming both locations are behind a router. The reason being if both use the same range how can your machine know when you mean one network and not the other. Careful selection of the IP range at home though can minimise this by choosing a non-standard private IP range. So a lot of home routers, the majority I've come into contact with anyway use 192.168.0.xxx or 192.168.1.xxx. The entire 10.xxx.xxx.xxx though, assuming the router allows you to do so is open and if you pick something in the upper half the chances of both places doing the same has to be very slim.

Is there any way to schedule an Internet connection reset?

Hello.
I live in a three-story house and have a Wi-Fi network set up using a Time Capsule and a couple of AirPort Express units. The Time Capsule, which is connected to the modem and is the initiator of the network, is on the second floor and there’s an AirPort Express each on both the first and third floors.
In India, we do not have the luxury of high speed unlimited access to the Internet. We can either opt for a 2Mbps connection (yeah, +scorching fast+, I know) that is capped at 2.5GB and allows unlimited access between 02:00 AM and 08:00 AM each day, or a 512Kbps unlimited connection.
Right now, I’m subscribed to the latter, but I made the mistake of traveling to the USA recently and, after having gotten used to the 16Mbps speeds for a month, I just cannot tolerate the incredibly slow speeds anymore.
Therefore, I’m thinking of switching to the 2Mbps connection. Since I download a lot of stuff though, I need to find a way to have the Internet connection automatically disconnect and reconnect at 02:00 AM and then get disconnected at 08:00 AM. Is there any way to get this done?
Putting my Mac to sleep and have it automatically wake up at 02:00 AM won’t work because the Internet connection will still remain connected on the Time Capsule and I will still get charged for the nighttime downloading. Is there any way to have my Time Capsule do the job for me—some Automator script or something, perhaps?
Any help would be greatly appreciated. Thank you.

How would that help though? I need the Internet connection to be reset, so that a new session starts after 02:00 AM, which will then be counted among the happy hours and won’t be chargeable. Restricted my Mac from accessing the wireless network is not the solution here.
Thanks for trying to come up with a solution though. Do let me know if you think of any other alternative.

WDS Set up - Help Needed! Airport Extreme with one Relay and one remote

Hi Guys,
I need a bit of help. I am feeling quite stupid and frustrated. I am having some difficulty with setting up a WDS network with:
Base station: Airport extreme (current version)
Relay: Airport Express (current version)
Remote: Airport Express (current version)
I start by cold resetting the three units. The Base station is connected via Ethernet. The setup I wish to get going is a simple base - relay - remote.
I go through the utility manager and set up the base station, first as "create a wireless network" enter the ISP details etc etc. Its green light. Everything is fine. Then manually configure the Base Station. Hold down option key hit Participate in a WDS. I then select main enter + and add the Mac Id's for the intended Relay unit and Remote Unit (12 character and numeric string). At this stage I am only adding the intended Relay unit and Remote units MAC number.
Question 1: Do I need to add the base unit's MAC number itself under: WDS Remotes? even I am setting it up as Main?
I am careful to note the security settings and the the Wireless Network name to match these in the relay and remote set up. Under the Wireless tab I leave the Radio Mode: as Automatic (802.11a/n - 802.11b/g/n). I make sure the base has "allow this network to be extended" ticked. Under Radio Channel selection I edit it to reference channel 1 for 2.4Ghz (5 Ghz leave as Auto). I am careful when setting up the Relay and remote to match the Radio Channel. (Although I tired many channels as I thought maybe interference was a factor and denying the fact its obviously my set up skills as a factor).
Question 2: Do you need to disable Guest networks? I would think it does not matter as I have tired turning it off and has not made any difference.
Under Access Control I leave as default, Not enabled.
Next I hit update and and error message comes up. WDS Error as it can not find other units. Ok fine as the relay and remote are not yet set up. So I ignore and can get to the stage where the base unit is working and green light with an internet connection.
I then proceed to set up the Relay unit. Doing the same steps as above with a couple of differences being I add the MAC numbers and select the WDS Mode (Relay for Relay and Remote for Remote. I add the Main base station (i.e Airpot Extreme MAC No.) when prompted and then + the Remotes MAC number. The same for the Remote except I only need to add the base station's main no.
Question 3. Do I need to add the Relay's own MAC number to its own setup? This seems doubtful as with the base station but tired with and without for good measure with no success.
The 2.4Ghz channels are all set to 1. Radio mode set to Auto. Although even when I try to manually set them to all identical it doesn't seem t help.
Then the problems begin. The base unit is Green and the Relay and Remote say they are not connected to the internet. I assume since I have not seen a WDS Error message then the units are set up correctly or as I ignored it on the base unit. But when click unignore the error seems to work itself out.
Question 4. I need help to understand why I have no internet. The remote / relay says something about no IP number and I don't really understand what I should do? Do I need to go back the Airport Utility Manager and start messing about with the TCP/IP, DHCP, NAT ? The base is set up PPPoE and the relay and remote are set to Bridge.
It is really puzzling me why the relay and remote flash amber with error messages related to the IP number? I have tried turning off the base station and router and then on again but no joy.
Can anyone please enlighten me or give me a few ideas? I am doing something very obviously stupid and I guess the fix is something simple that I have overlooked.
I did spend the time and go through the threads and search online, So I am not trying to waste anyone's time I referenced the two links to get a second opinion:
http://broadcast.oreilly.com/2009/03/taming-an-airport-express-wds.html
http://www.macobserver.com/tmo/article/settingup_an_airport_relay_with_airportexpress/
Any help much appreciated!

Welcome to Apple's discussion groups.
My WDS experience is limited to "main" and "remote" configurations (no "relay"), so I'm not posting from direct experience, but below is what I think would work in your case.
I go through the utility manager and set up the base station, first as "create a wireless network" enter the ISP details etc etc. Its green light. Everything is fine. Then manually configure the Base Station. Hold down option key hit Participate in a WDS. I then select main enter + and add the Mac Id's for the intended Relay unit and Remote Unit
I don't think the "main" unit needs to be told about the "remote" unit, only about the "relay" unit.
Question 1: Do I need to add the base unit's MAC number itself under: WDS Remotes? even I am setting it up as Main?
You'd never enter the MAC address of a unit into its own configuration, if that's what you mean. I also don't think that you'd need to enter the MAC address of the main into the remote and conversely.
I am careful to note the security settings and the the Wireless Network name to match these in the relay and remote set up. Under the Wireless tab I leave the Radio Mode: as Automatic (802.11a/n - 802.11b/g/n).
Five things have to match in a WDS configuration: network name, encryption type, network password, band, and channel.
I make sure the base has "allow this network to be extended" ticked.
I don't think that's important for a WDS configuration.
Question 2: Do you need to disable Guest networks?
I wouldn't think that matters.
Under Access Control I leave as default, Not enabled.
That's fine.
WDS Error as it can not find other units. Ok fine as the relay and remote are not yet set up.
Right.
I then proceed to set up the Relay unit. Doing the same steps as above with a couple of differences being I add the MAC numbers and select the WDS Mode (Relay for Relay and Remote for Remote. I add the Main base station (i.e Airport Extreme MAC No.) when prompted and then + the Remotes MAC number. The same for the Remote except I only need to add the base station's main no.
I think this should be the MAC address of the relay station, not that of the main station.
Question 3. Do I need to add the Relay's own MAC number to its own setup?
No.

PSE7 Restore to different PC fails to update drive letter in catalog

I'm trying to simply copy my catalog and photos from my desktop to my laptop to have with me when I'm away. From all the discussions it seemed like backup/restore was the best method in order to preserve all the tags and other data associated with the images.
Source Drive:
Volume in drive H: is Data
Volume Serial Number is 30AF-58D3
Catalog: RH Main
Picture Folder: h:\My Documents\My Pictures
Catalog Folder: h:\My Documents\Adobe\Photoshop Elements\RH Main
Backup Destination:
Volume in drive M is OneTouch4 1-TB Serial number is e79a:bf54
Now on the laptop I run the restore and choose 'Hard drive/Other Volume' and locate the Tally file on drive X: which is mapped to drive M on my desktop. It was simpler to restore across the network rather than moving drive M to the laptop.
Under 'Restore Files and Catalogs to' I choose 'New Location', specify D:\, and check 'Restore Original Folder Structure'.
On the laptop:
Volume in drive D: is Apps_Data
Volume Serial Number is 3069-7A44
After the restore is complete, all of my photos are exactly where I expect them, D:\My Documents\My Pictures. The catalog is in D:\Catalog.
The problem is that there are no thumbnails displayed for any of the photos. Examining the properties of each reveals that they are presumed to be on drive H: - their original location on my desktop.
I could have easily copied the files myself, but I was counting on restore to do what I could not easily do - which was to update the database to reflect the correct location of the restored files. After all, restore PUT them there. Something must have convinced it that the drive letter containing the restored photos was still H:, but I'm at a loss as to how it could have come to that conclusion.
Am I missing a step or am I expecting too much from backup/restore?

The only drive visible to the laptop is X: which is mapped to M: on the desktop - the destination for the backup. The drive containing the original images on the desktop is H:.
Automatically search and reconnect is checked.
Update thumbnail doesn't work. Here's what's funny. Take a single example, a file named DSC_0005.JPG. I choose update and it starts scanning on D: and I can see it run through My Documents, My Pictures, and all of its subfolders. It turns out there are no less than 10 occurrences of that file name under My Pictures - each of them in a different sub-folder of course. So I let Update Thumbnail run and ended up at the reconnect screen where I can go find it manually. Why it didn't find any of those 10 files is a mystery. So I reconnected manually by browsing to the correct DSC_0005.JPG file - formerly at H:\My Documents\My Pictures\2009 01 01 but now on D: at the same path.
Next I choose the thumbnail adjacent to it on the screen, DSC_0006.JPG. I check the rmf.3.cache file and the only entry in it is the folder that I just matched DSC_0005.JPG from - which is the same folder that contains DSC_0006.JPG. The process again runs for quite some time searching C: & D: for DSC_0006.JPG. Once again I'm presented with the Reconnect Missing Files dialog with no file suggested on the right side. So even with an entry in the cache pointing to D:\My Documents\My Pictures\2009 01 01, a folder containing a file named DSC_0006.JPG, it could not find a match!
Back in PSE5 I had performed this reconnect on one file and then again on the rest as described on your web page and it worked as you described. So I'm familiar with that process but have not needed it lately, until now.
The backup/restore functionality is so basic that I'm sure they tested it to some degree and it must work for some, otherwise many others would likely be griping. So there must be something unique to my setup that it's unable to come to grips with. Surely their internal testing of the restore feature included a test to restore to a different drive.
Maybe they made the restore too smart. It certainly restores the file to the correct location based on the options I selected and the file retains its original name - but the database thinks it hasn't moved from the original location.

How to unpair bluetooth headset during charging

I have an old Jabra BT500 and a iphone4. One thing I really like is that the Jabra BT500 unpairs while it is charging. But the sound quality was ok. So I recently upgraded to the Plantronics Voyager Pro+ and discovered the new headset doesn't unpair while charging, it is always connected.
I also tried another headset and had the same issue. I'm wondering if the newer headset has this new default behavior.
Any ways to get the original behavior or is this a specific issue with the Voyager?

Yes, all headsets do disconnect if you manually unpair or turn off bluetooth. But I want this automated.
With the BT500, I have this scenario
BT500 paired with iPhone 4 and working properly
After I'm done using it, I connect BT500 to the power plug for recharging
BT500 automatically unpairs (.ie no bluetooth connection). This also saves battery on the iPhone.
If I need to use the BT500 again, I unplug the power and the BT500 automatically pairs and reconnect.
With the Voyager Pro+ (and another newer headset), #3 doesn't work. It doesn't automatically disconnect.

Airport Extreme & Samsung SMART 3D TV UE46ES8080

Hey Guys!
I have a Samsung 3D LED TV (UE46ES8080) and i tried to connect it to my Aiport Extreme. Unfortunately, that didn't work.
Is there anybody that can help?
Thanks!

Ok, how about some more details on both your AirPort and the wireless capability of your TV:
Which generation is your AirPort Extreme?
What Radio Mode is it configured for ... Automatic, 802.11n, etc.?
What Radio Channel is it configured for ... Automatic, 1-11, etc.?
For the TV, is the wireless adapter built-in or an external USB device?
If external, it this provided by Samsung or another vendor? If the latter, which vendor?

HP Servers NIC Teaming with Cisco Nexus 2000/5000

I have number of HP switches that will be connected to Cisco Nexus 2000/5000 switches.
In HP Servers, there are multiple options for NIC teaming. I like to connect each port in a NIC card to two different Nexus 2000 switches extension to Nexus 5000 switches. Nexus 5000 switches will be configured as VPC for clustering.
Wanted to know what whould be the best NIC teaming option from the followng HP Server's NIC Teaming options:
Automatic
802.3ad Dynamic with Fault Tolerence
Switch-assisted load balancing with Fault Tolerance (SLB)
Transmit load balancing with Fault Tolerance (TLB)
Transmit Load Balancing with Fault tolerance and preference order
Network Fault Tolerance Only (NFT)
Network Fault Tolerance with Preference Order

Nexus switches only support LACP (802.3ad) or ON mode. So, to match your server config with your switch, the first option is the best one to use. I think, SLB is a Microsoft propriety protocol.

Moving part of a catalog to network drive.

I need some good advice for a catalog of 13k+ photos that I'm trying to clean up. I'm using Elements 7, I have purchased Elements 11, and am planning to install it soon. Part of my photos are physically located on my hard drive, and part are on a network drive mapped as J:. Elements finds these photos on J: but I don't think that the Elements Catalog is aware that J: is a network drive/removable drive. It looks for them every time I open Elements, making the program very slow to start up. Should I use the "move to removable drive" to move these photos? How will Elements treat these photos that have been sent to a removable disk? Will I still be able to see thumbnails of the photos and search through my tags for them? If I copy my photos to a new drive, but still call that drive J: will Elements be able to find them? And finally, if I perform this "move to removable disk" task, should I do it now with Elements 7 or update to Elements 11 first? Please help. Joanne

If the Organizer is slow to start and seems to be searching, you should check two things:
- that you have not set the 'watched folders' service to look at the network drive (file/watched folders menu)
- that in the preferences, files, you don't have checked automatic search and reconnection.
If you can access your files on the network drive from the organizer and see the thumbnails, no need to worry. You can move files from your internal drive to and from the network one by the file / move menu or by dragging and dropping folders in folder view. The organizer should not consider the network drive differently from an external USB drive : if such a drive is not physically connected, you'll get 'missing files'. Only the thumbnails which are stored in the catalog will show. It's different from files on a CD/DVD : if they are not connected, you'll get an offline media warning.
Only the catalog itself (the database) cannot be stored on a network drive; however it can be stored on an USB external drive.
If you want to upgrade to PSE11, be sure to make a full backup on a second external drive (such USB drives are affordable today). Note that from that backup, you are able to restore the files not only on their original location, but also in custom location, for instance in the internal drive of another computer (even if the original files are scattered over several internal or external drives).
If you install PSE11 on your present computer, you should be prompted to convert the existing catalog(s) to the new PSE11 format without having any files or folders to move or copy. That conversion does not change anything to your present PSE7 catalog, which is still working as before.

Jco.server.max_startup_delay

SAP Note 730870 say:
Q 25: A RFC sender channel is registered at a SAP Gateway which is shutdown. Does the RFC sender channel automatically reconnect to the SAP Gateway after it is available again?
A: The SAP Gateway is shutdown due to e.g. offline backup of the R/3 database while a RFC-Adapter sender channel is registering at this SAP Gateway. After restarting the SAP Gateway, the RFC sender channel does not seem to automatically perform a reconnect.
Actually the RFC sender channel will try to reconnect to the SAP Gateway. If this reconnect fails, the next reconnect attempt is made after a waiting period of 1 second. If the next reconnect fails also, the waiting period is doubled and so on. This will lead to a reconnect timing of 1, 2, 4, 8, ..., 3600 seconds. Saving recources is the aim of this technique.
If not configured, the maximum waiting time is defined in the middleware layer of SAP JCO, which is 3600 seconds. But this maximum time can be configured for each RFC sender channel in the XI Integration Directory. Open the Advanced Mode for the RFC Server Parameter.
Before SP 12: Add a line to the table and use 'jco.server.max_startup_delay' as name and the maximum number of seconds to wait between reconnect attempts as value.
Since SP 12: Enter the maximum number of seconds to wait between reconnect attempts in the field Maximum Reconnect Delay.
My question:
Where to find the parameter jco.server.max_startup_delay?
Regards,
Dirk-Jan Kloezeman

Hi,
When you are connected to the J2EE Engine choose the tab 'Cluster' and open the appropriate server node in the tree. Then open the 'Services' node. There you can see the entry 'SAP XI Adapter: RFC'.
In this you will find this parameter.
Source - restart the RFC Adapter - visual admin

Based on your provided diagram, the router would be providing IP address for all network clients connected to either the router or to the Express. What is the make & model of this router?
It is a "linksys broadband router wireless g 2.4 ghz". Yeah the router provides the IP adresses.
I don't know if it is important but the router and the APExpress are connected via two dLAN adapters from devolo.

WiFi says I need a password but there isn't one when I connect with my phone

The title says it all. I'm trying to connect to McDonald's public WiFi and when I connect with my phone, it works normally, but when I try to connect with my Mac, it says that either the connection has timed out or I entered the wrong password.
I'm running OS X 10.7.4 Lion.

I've never actually managed to connect to the network, it automatically disconnected and reconnected to my usual one.

Oracle databaguard maximum maximum availability mode

Hi All,
My database is in maximum availability mode at 9.2.0.8:
SQL> select protection_mode from v$database;
PROTECTION_MODE
MAXIMUM AVAILABILITY
SQL> show parameter log_archive_dest_2
NAME TYPE VALUE
log_archive_dest_2 string SERVICE=XXX.world LGWR SYNC
AFFIRM,
SQL>
Oracle Documentation says:
Maximum availability mode provides the highest level of data protection that is possible without affecting the availability of the primary database. This protection mode is very similar to maximum protection where a transaction will not commit until the redo data needed to recover that transaction is written to both the local (online) redo log and to at least one remote standby redo log. Unlike maximum protection mode; however, the primary database will not shut down if a fault prevents it from writing its redo data to a remote standby redo log. Instead, the primary database will operate in maximum performance mode until the fault is corrected and all log gaps have been resolved. After all log gaps have been resolved, the primary database automatically resumes operating in maximum availability mode.
and it also says.....
The NET_TIMEOUT attribute of the LOG_ARCHIVE_DEST_n parameter specifies the number of seconds the log writer process on the primary system waits for status from the network server process before terminating the network connection. The NONET_TIMEOUT attribute reverses or undoes the timeout value that you previously specified with the NET_TIMEOUT attribute.
If you do not specify the NET_TIMEOUT attribute (or if you specify the NONET_TIMEOUT attribute, the primary database can potentially stall. To avoid this situation, specify a small, nonzero value for the NET_TIMEOUT attribute so the primary database can continue operation after the user-specified timeout interval expires when waiting for status from the network server.
If the log writer process detects a network disconnection, even one that was terminated due to a network timeout, the log writer process automatically tries to reconnect to the standby database. The log writer process does this to resolve network brownouts and false network terminations. In most cases, except when the network is physically broken, the log writer process is able to automatically reconnect to the network.
The log writer process continually attempts to reconnect to the standby database for a period of time that depends on the data protection mode currently set for the primary database. Use the following time estimates as a guideline for how long the log writer process will try to reconnect to the standby database:
In maximum protection mode, the log writer process tries to reconnect for approximately 5 minutes.
In maximum availability mode, the log writer process tries to reconnect for approximately 2 minutes.
In maximum performance mode, the log writer process tries to reconnect for approximately 30 seconds.
question is:
1>Does that mean if primary database is in maximum availability mode and if there is network issue and it cannot communicate with standby database, it will freeze or stall for 2 minutes and then operate in maximum performance mode.
That freeze for 2 minutes in production is pain :(
2>Does it also mean,
In maximum performance mode primary database will freeze fro 30 seconds and then move on.
3> To convert from maximum availability to maximum performance do I need to bounce the primary database at 9.2.0.8

I guess I haven't asked the question correctly,
I have asked 2 different question:
1> do you need to mount your database to downgrade the protection mode, I needed confirmation for that at 9.2.0.8
below is link which shows how to downgrade mode:
http://www.idevelopment.info/data/Oracle/DBA_tips/Data_Guard_9i/DG_70.shtml
2> question is all together seperate,
staying in maximum availability mode what happens if you use 'LGWR ASYNC' or 'ARCH' for log shipping.
Why I am asking this question is because, oracle recommends to use 'LGWR SYNC AFFiRM' for maximum availability mode.
I have tried before 'LGWR ASYNC' or 'ARCH' in maximum availability mode and it worked.
Has any one tried 'LGWR ASYNC' or 'ARCH' in maximum protection mode. does db freezes or stalls.
3> When database stalls for 2 miuntes when it cannot connect to dataguard in maximum availability mode, I cannot see any trace files generated, nothing is written in alert log and nothing in listener.log

My backup never succeeds- now I need to Restore.

I have been using PSE since version 3 and now use version 11. In all that time I have always had problems getting a backup to go all the way through to completion. I normally end up with the copied files as B???????.* and a catalog.buc file. No *.tly file.
Obvioiusly when I want to restore I cannot do it via the restore command because it needs the tally file.
As it happens, my current catalog includes multiple copies of some files on three hard disks so when one of my hard disks crashed all has not been lost.
I have tagges all the files that are on the crashed drive and then identified those with a duplicate elsewhere and those without. I now know that I need to recover about 1000 files and I think that most of them are on my backup set that has no tally file.
I know that I could go through the B??? files one by one and find the files but that will take a long time. Can anybody suggest a procedure to speed it up?

A more general question might be:
"What can you recover from an incomplete pse11 backup, where the backup.tly file is missing ?"
Note : I am convinced that the lack of the backup.tly file means at least a part of the media files have not been copied, and can't be recovered.
The good news is that the catalog.buc is a copy of the database, the catalog.pse11db file.
If you need to restore because the catalog has been messed up, you can always rename that catalog.buc and use it to replace the old catalog.
Now, one of your hard drive has failed. I suppose your backup is on an externel drive like J:
If your catalog is still valid (it was not on the failed drive), ok. Otherwise, rename and copy the catalog.buc to use it.
If you search for missing files, you'll find all the files which were on the failed drive.
Each missing file has a copy in the backup folder of your J: drive.
Is there a way to reconnect the missing file to the 'B0000...' file in the backup folder ?
Yes... but I don't see a way to do that automatically.
The reconnection feature lets you browse to your backup folder. It shows the icons of the corresponding files. The problem is that the automatic restoration process will recognize the file has been renamed and show a message requiring you to confirm the reconnection. You have to do that for each individual file. To reconnect 100 files is quite feasible, for 1000... you are right, that will take a long time.
If you succeed in this task, you may want to move the reconnected files from the backup folder to one of your internal drives.
For the reason you can't complete a full backup, the usual reason is the presence of unrecognized file types, mainly video.
