File Sharing drops regularly, Time Machine Backups are delayed on OSX 10.7.3. Solution?

Hi there folks,
I'm having an issue with the new 10.7 server. We're running 10.7.3 Server on an Late 2006 XServe with 10GB RAM , connected to a Drobo Pro for Time Machine Backups of our 50+ users via our internal network.
Recently, Time Machine backups have been getting delayed, stating that they can't connect up to the backup drive (which is out Drobo Pro handling 16TB of space). The Drobo Pro hass not unmounted, and all the IP Addresses coming from and going to the Server handling the backups will still ping.
We've also be having trouble with Server resident drives and shared folders that people can mount using the ⌘+K shortcut or "Connect to Server" option in finder. People will choose the IP address, and finder will think for a few minutes then give an error stating that it cannot connect the the specified IP. The only way I can reestablish connection to the file sharing through a remote computer is to remote or physically login to the server, then go into System Preferences and turn "File Sharing" off, then on again. After that, the ⌘+K on a remote machine can find the drives again.
It's driving me crazy why this is ocurring. I don't know why, and people in the office are beginning to complain that they can't access certain files on the servers or are worried because their backups are not completeing.
It should also be known that a majority of the machines we have in the ofice are still running 10.6.8, with only a handful on 10.7, as we haven't had the time to make the major switchover yet.
I'm not the best when it comes to server software or Unix CLI managment (the office outsourced our Network Admin to the east coast), so I'm a bit stumped.
Does anyone have any suggestions to try? Is there a link between the number of Time Machine Users and the connection failures? Should I just tel the NetAdmin to create a script that will restart the File Sharing protocol on the server every couple of hours?
Hopefully someone will be able to help.
Thanks,
JYHASH

I started having connectivity issues to my 10.6.8 server from my 10.7 client immediately after updating the client to 10.7.3. FWIW. Takes forever to connect, when it does. After just milliconds before.

Since upgrading to Lion, my time machine backups are failing - error message: The backup disk image "/Volumes/Jackie Scanlon's Time Caps/Jacqueline Drabczynska's MacBook.sparsebundle" could not be accessed (error -1). Any ideas?

After Server 4.1 update, Time Machine backups are huge

Hi,
After updating to Server 4.1, every one of my Time Machine backups for the machine (Late 2012 iMac) running OS X Server (which is backed up to a USB connected drive) is between 3GB and 7GB. When a backup finishes, I can immediately force a manual backup and it's >= 3GB.
Using the timedog utility, I narrowed the problem down to the OS X Server install, the largest file being:
/Library/Server/Wiki/Logs/postgres-xpg.log
Every 10 seconds, an entry similar to the following is added to this file:
2015-04-16 23:04:31 XPG.5941: matched path for pg_receivexlog file: /Library/Server/Wiki/Database.xpg/backup/000000010000006300000035.partial
This particular log file is around 3GB in size. It appears to have every log entry since I installed OS X Server December 2013. I find it odd this is happening in the Wiki directory as the Wiki service is disabled. I am using the following services:
Caching
Calendar
Contacts
File Sharing
Time Machine (for my Macbook backups)
I went into Time Machine (on the iMac) and deleted all the backups for /Library/Server/Wiki and that freed up 160GB. I could just exclude that from backups, but I don't want to do that. I would like to know why these entries keep getting put into that log and also why, if those entries are appropriate, the log is not rotated.
Any help would be appreciated!
Thanks, Patrick

Hi Patrick,
That particular log-file has had an issue for some time now.
Even when the wiki is not loaded the wiki proces generates errors which keeps on filling this log.
Exclude it from the backup simply solves your backup issue.
However there are some suggestions for "fixing" this enormous log around in the Apple Support Community.
I don't worry too much about it anymore, but you can generate a new file and throw out the old for instance.
As long as you have enough storage you're fine.
Some usefull steps for a fix are mentioned here:

My Time Machine backups are significantly larger, and slower, over WiFi than Ethernet

My regular hourly backups from my Time Capsule began acting up a month ago. They were abnormally large (25-100 MBs) and took a long time--once, six hours.
I connected my Time Capsule to my MacBook Air through ethernet to repair the disk through Disk Utility, (I turned Airport off on the Air, but not the Time Capsule), and then to rebuild the Spotlight index for the Time Capsule.
Backups over ethernet work just fine now. The backup will happen in two parts, of around 200 KB each, and take two or two and a half minutes. But when I turn Airport on the Air back on, reconnect to the WiFi network, unplug the ethernet cable, and immediately start a new backup over WiFi, the two parts balloon to around 20 MB each, and the backup takes hours.
This is a backup over ethernet, which took 2 minutes, 21 seconds:

I live in an apartment building so there are a number of WiFi networks around.
Not to mention cordless phones, microwaves, etc., any of which can interfere.
On iStumbler, my network shows up twice--once on channel 149, with signal strength of 50-65% and noise of 15%--and again on channel 10, with signal strength of that wildly varies from 20% to 90% and noise of 20%. Other networks in the building are on channels 1, 2, 6, and 11. The graph of channel 149 is very smooth, while the graph of channel 10 is choppy.
It's probably using 149, as those numbers are pretty good. Press Alt/Option before clicking the Airport icon in your menubar to see which band it's using.
Watch the band it's using while running a backup. Try other channels in the area of 149. Unfortunately, it's a bit of a "hit and miss" thing.
Why are there two networks? Is that part of the problem? My Time Capsule is located about three feet right and a foot below my desk, so I can't think of a reason why it wouldn't be 100% for both channels.
It's a dual-band router. As I understand it, OSX will pick the best signal.
I really want to know I have a clean, safe, accessible back-up before I replace it though. Right now I don't trust the Time Capsule.
Do at least your last backup via Ethernet.

Fix file size of local time machine backup

Hi all,
I'm having an issue where after copying over Backups.backupdb from my 1.5 GB external drive to another iMac, it shows that folder as now being 6.27 TB. The local disk on the iMac is 1 TB.
The resson I copied over Backups.backupdb to the iMac is that suddenly one day when connecting the external drive to my MacBook, (This external drive was used with the MacBook as a Time Machine backup) I was promted with a warning that there was a problem with the external drive and that I should copy the files over to another location and reformat the external drive. After copying over the files on the external drive to the iMac I then reformatted it.
So, the issue is that Finder reads that the Backups.backupdb is 6.27 TB and I can't copy it back over to the newly reformatted external drive.
If anyone has any insight, I would really apreciate it if someone could tell me if it's possible to:
modify Backups.backupdb and it's contents sitting on the iMac to show it's actual file size, correct the permissions and extended attributes?
copy over Backups.backupdb to the external dirve in some other way (I tried via Terminal but with no luck)?
Thanks in advanced!

I had the same problem!
Time machine folder was using around 230GB on a 1Tb disk space.
Had to format the disk because Time Machine was stucked at "preparing backup" or something similar after 6 months without using it.
But after transferring it's main folder to my desktop, it is now showing 1.6Tb size!
I can't move it back to the 1TB disk after format and I as need to do a clean reinstall to my Macbook Pro HDit seems I will have to trash my Time Machine saved folder an loose all it's contents if I can not find a solution.
Is there any fix?
Or I just have to let go this folder?
Even folders inside it, like documents or desktops from previous backups are huge in size!

Is there a way to recover files deleted from a time machine backup

My time machine backup drive was full so I wanted to delete some of the Virtual Machine files created with VMWare Fusion from the time machine backup. I accidentally deleted them all, instead of just some older ones, so I want to know if there's a way to recover or salvage the files I deleted from time machine.

If is possible do you have a Time Machine backup, What type of files are missing?

Time Capsule: Shared Disk or Time Machine Backup

Hi
I am planning to buy a 500GB Time Capsule, but i have some doubts that maybe you could help me.
I know that Time Capsule is not just for making time machine´s backups. I know this because on apple website it indicates that works in PC and Tiger so that means that it is also a shared disk.
What i want to know is if i have to choose between a shared disk or a time machine backup. What i want to do is to assign 250Gb for time machine and the rest for a shared disk.
Is that possible?
Thanks

Almost certainly you will be able to use Time Capsule for both Time Machine backups as well as shared file storage. However - a couple of things to keep in mind:
1. because Time Machine continues to back up files over time, the amount of drive space it uses will also continue to increase (potentially to the limit of the available free space).
2. there is (unconfirmed) speculation that you may not be able to partition the drive built into Time Capsule, so that you may not be able to force an upper limit to Time Machine's usage of the drive without of course keeping close track of it yourself.

Help recovering files from an incomplete time machine backup.

I set up a network drive as a time machine backup for my mac and my wife's. As the initial backup was being created, her hard drive crashed!
Most of her drive had been backed up. After some reading I was able to repair the .sparsebundle file which contained the partial backup and mount it. Once mounted there is a .inprogress file which is the partial time machine backup. I can right click and choose "Show Package Contents". This lets me browse the folders backed up folders and see that most or all of her files are there, I have even opened a few office documents and saved a copy.
The problem is that if I try to move any of the files or folders I get Error code - 1426.
I'd rather not have to individually open each document and save as. Is there another way to recover the files? Does anyone know a way to explore the contents of a package in the command line?
Thanks

try copying the files from terminal.
use the following terminal command
ditto --noacl path/to/sourcedirectory path/to/destinationdirectory
to get a path to a directory you can drag it to the terminal window.
make sure all the spaces in the above command are there.

Time Machine backups are bigger than expected

Hi everyone,
I was wondering if anyone would know why, all of a sudden after a day or two ago, my Time Machine is suddenly insisting on backing up well over 4GB at a time? Before then my backups would almost always be below the 100MB mark. Has some update happened that would have caused this?
I have looked in Console but unfortunately am none the wiser. Is there some way of finding out a list of the files Time Machine is actually backing up? If so then I'd be able to track down this problem since I am fast running out of space on my Time Machine backup drive!
Many thanks for listening...
:-Joe

Jowie,
Consider the following info that I have gleaned, some of it may explain some it.
*Incremental Backups Seem Too Large!*
Time Machine performs backups at the file level. If a single bit in a large file is changed, the WHOLE file is backed up again. This is a problem for programs that save data to monolithic virtual disk files that are modified frequently. These include Parallels, VMware Fusion, Aperture vaults, or the databases that Entourage and Thunderbird create. These should be excluded from backup using the Time Machine Preference Exclusion list. You will, however, need to backup these files manually to another external disk.
One poster observed regarding Photoshop: “If you find yourself working with large files, you may discover that TM is suddenly backing up your scratch disk's temp files. This is useless, find out how to exclude these (I'm not actually sure here). Alternatively, turn off TM whilst you work in Photoshop.” (http://discussions.apple.com/thread.jspa?threadID=1209412)
If you do a lot of movie editing, unless these files are excluded, expect Time Machine to treat revised versions of a single movie as entirely new files.
If you frequently download software or video files that you only expect to keep for a short time, consider excluding the folder these are stored in from Time Machine backups.
Files or folders that are simply moved or renamed are counted as NEW files or folders. If you rename any file or folder, Time Machine will back up the ENTIRE file or folder again no matter how big or small it is.
George Schreyer may be describing what you are experiencing: “If you should want to do some massive rearrangement of your disk, Time Machine will interpret the rearranged files as new files and back them up again in their new locations. Just renaming a folder will cause this to happen. This is OK if you've got lots of room on your backup disk. Eventually, Time Machine will thin those backups and the space consumed will be recovered. However, if you really want recover the space in the backup volume immediately, you can. To do this, bring a Finder window to the front and then click the Time Machine icon on the dock. This will activate the Time Machine user interface. Navigate back in time to where the old stuff exists and select it. Then pull down the "action" menu (the gear thing) and select "delete all backups" and the older stuff vanishes.” (http://www.girr.org/mac_stuff/backups.html)
*FileVault / Boot Camp / iDisk Syncing*
Note: Leopard has changed the way it deals with FileVault disk images, so it is not necessary to exclude your Home folder it you have FileVault activated. Additionally, Time Machine ignores Boot Camp partitions as the manner in which they are formatted is incompatible. Finally, if you have your iDisk Synced to your desktop, it is not necessary to exclude the disk image file it creates as that has been changed to a sparsebundle as well in Leopard.

HT201250 Time Machine backups are extremely slow

Time Machine backups filled an older, smaller external HD, began deleting oldest files. TM backups began to be very slow, I assumed because of the deletion of older files. I replaced external HD with a new LaCie 3.0TB external HD (p9233). Backups are still very slow, take a very long time. It appears TM is backing up all files each time it runs - literally hundreds of thousands of files each backup when only a few files should have changed from one hour to the next. I have tried on and off as well as setting up TM anew, nothing seems to affect time and speed. Any help?

Can no longer connect to shared drive for Time Machine backups

I have a Firewire drive connected to my iMac and sharing enabled. 2 MacBook Airs then connect wirelessly to the same network and backup to the drive.
It has worked perfectly for the last couple of years with Lion and Mountain Lion.
Yesterday I upgraded to Mavericks and now neither laptop can see the shared drive in Time Machine, although the drive displays quite happily in Finder.
I have disabled and re-enabled sharing. Booted and re-plugged the drive in and still when I go to Time Machine preferences and select drive, nothing is listed.
Any ideas?

After hours and hours of constant searching and testing I still can't get it to work?
Any ideas?
I think sharing has changed in Mavericks.

How can I tell if my Time Machine backups are encrypted?

Hi - I would really appreciate it if someone could help me find out if my Time Machine backps are actually encrypted.
I know that there is an 'encryption' option when choosing a disc for Time Machine to backup to, but the problem is I cannot remember whether or not I actually ticked it (as it was a couple of years ago).
Other info that might be helpful:
- The disk I use Time Machine to backup to is actually a Apple Time Capsule
- I do have FileVault2 enabled on my mac
- I have never encrypted the Time Capsule disc itself (via Disk Utility or anything similar)
- One possible clue might be: When I go into Time Machine preferences, and click on 'Select Disk...' (as if to choose another disk to back up to), and select the disc that Time Machine currently backs up to (i.e. the Time Capsule disc), it does show an 'Encrypt backups' checkbox at the bottom of the window... however this checkbox is unchecked and also greyed out.
Thanks in advance

- Because I originally created this Time Machine Backup (to the Time Capsule) back in my 'OS X Lion' days,
I wondered; you posted in the Mountain Lion forum, but your profile still says Lion.

Correct (as of now, anyway). You cannot encrypt existing network backups. I doubt that will be available in the future, and would take forever.
- The only way to encyrpt my backups now, moving forward, is to remove this Time Capsule disc (from Time Machine Preferences), and start all over again ensuring that I check the checkbox next to 'Encrypt Backup' when selecting the Time Capsule's disc to backup to.
Well, in theory it's possible, but would take forever, squared.
You could archive the TC's contents to a USB drive connected to it, per #Q6 in Using Time Machine with a Time Capsule).
Then delete the original, start a backup with encryption, and as soon as the encrypted sparse bundle is created, cancel the backup.
Mount the sparse bundle, open the disk image, and delete the Backups.backupdb folder inside it.
Connect the USB drive to your Mac, mount that sparse bundle, open its disk image, and copy the Backups.backupdb folder to the one on the TC.
Depending on how large the sparse bundle is, that could easily take a couple of days, at least, even connected via Ethernet.
Just for testing one day, I encrypted a very small set of existing test backups on a F/W 800 drive - 6 dated backups using a whole 12 GB. Took an hour.
An alternative would be, just do the "archive" and keep the USB drive "on the shelf" for a while. You can always connect it to your Mac and access those backups via the Browse Other Backup Disks option.
Trying to keep a couple of years worth of backups usually isn't a good idea. It's a very complex structure, so the odds of damage increase, it takes much longer to populate the TM browser, and it works slower and slower, and if you didn't need something for 6 months, are you really going to need it in 2 years?

If I restore My Mac OSX Snow Leopard can I get all my files back from a time machine backup made on a portable hard drive?

I want to restore my MacBook Pro running Snow Lepoard, I made a time machine backup on a portable hard drive, can I get all the files back when resseting the OSX from the Hard Drive?

If you're using the Mac App Store version, there is initially no clean install option unless you're running the installer on a different drive or partition; your existing data will remain as is. If you're doing it from Lion's recovery partition or using the USB flash drive after erasing the internal drive, yes.

Retrieving work files/data from a time machine backup off another computer

If I create a time machine backup on one imac (imac 1) onto an external drive, I want to know if I can use this backup on another mac (imac 2) and restore or retrieve the old work files as and when required work from the external drive (time machine backup)? onto imac 2?

You can't use Time Machine for Restoring on iMac 2 (if you made an TM Backup with iMac 1), but you can easily drag files from the "Time-machine-Backup-volume" in Finder on your iMac 2!

Time Machine Backups are stuck in my trash...

OK, benefit of hindsight. NEVER try to delete Time Machine backups by putting them in your trash. That aside... I did that. So... How the **** do I get them out?
- without having to format the drive Time Machine is on... (this is full of other files)
- I don't mind deleting all my backups...
- Have tried emptying trash in every conceivable way inc. using Clean My Mac
Somebody? Anybody?

Try restarting and then emptying.
Try holding down the option button while trying to delete the Trash. If that doesn’t work, here is some more information.
Trash – Error Code 8003
Trash Permission Error
Trash Permission Error (2)
Trash Can’t Empty – Big Files
Trash – Can’t Empty or Move File To Trash
