Abysmal speed for TM backup on NAS

I have tried a couple of times to connect a ICYBOX NAS to my MacPro with Snow leopard through a Belkin F5D8235-4 wifi router using Time Machine to backup my several internal HDs onto the two WD20EARS in the Icybox.
It started backing up, but the speed has been abysmal, after 10 days it had backed up around 1TB, around 1.2 MBps. Looking at the network window of Activity Monitor I see transfers are in bursts of around 4.3 MBps with an interval between bursts of around 3-4 seconds, while a second attempt today, after replacing all cables with known Cat5E ones I clocked 14 seconds between bursts.
Is this burst transfer behavior normal? What is the reason for it?
What should I check?
What can I try to improve the transfer speed?
I tried connecting the NAS to the MacPro directly, but I do not know how to let the Mac see it (how do I get its address, with the router I can see its address in the configuration page). Also, Can I use this connection on one of the Ethernet ports and have internet traffic on the other? How?
Thanks in advance for any help, although I am a first hour Mac users, networks are not my forte.

A little update. After fiddling around a bit I made it work on the second port, by configuring it when it was connected through the router to have DHCP on and a fixed IP address, and then moving it to the other port, and putting this second in the hierarchy so that internet goes on through the first port.
Transfers sped up a bit, something like double the previous speed, now it does 10GB in an hour, but this is still waaaaay less than it should. Any ideas on what can be wrong? Also, I have the impression that now all my web page connections have a sort of hiccup before loading (but it is true that there is this background copying going on, now)

Which NAS you recommend for SMB backup storage

Synology and ReadyNAS would be my first choices in this category. I have and use both and love them. I've had quite good success with Buffalo as well with clients. Nearly all storage engineers that I know when choosing this type of storage, like Kooler, choice Synology and ReadyNAS.
For backups and archives specifically I have had good luck with Drobo too.

For me it's always between Netgear and Synology. Now I'm back to Netgears (being a green guy here I cannot tell reason in public).For anything bigger then 2 SATAs in RAID1 economically reasonable to "roll your own" backup appliance. Recycled Dell R7xx and again recycled Windows Server 2012 R2 (because of SMB3 and decent backup-ready dedupe) appliance is very hard to beat! In case you don't have old server xByte has a stack of reburbished ones they sell cheap.--Planning to buy a NAS storage for our backups.Very small environment with VMware host, 7 VMs, Veeam backup.Total backup size 200GB, daily increment is around 7-10GB (Compressed).Will use the NAS for backup storage only and nothing else.Which brand do you recommend or use at your SMB locations:SynologyQNAPSeagateNetgear ReadyNASBuffalo

Corrupted Time Machine Backup on NAS

I'm just going to explain the steps leading to my problem so it's clear:
1. I created an encrypted sparsebundle disk image for backing up to a NAS at my workplace.
2. The time machine was working fine for a couple of months until my Macbook started shutting down randomly.
2a. This would always happen with CPU heating up to 94 degrees C and fan cranking up to 6400+ rpm. So I thought it was an issue with the heatsink.
3. I decided to do one final TM backup before giving it for service. I tried a number of times to backup to NAS but everytime the machine would just shut down in between leading to "unsuccessful backup".
3a. The CPU would still heat up during the backup but I was really desperate to do that one backup before giving it for service. So I tried doing the backup in a cold room (thinking it was just an overheating issue)!! The room temperature was close to 10 degrees C in the cold room and CPU temperature never rose abouve 60 degrees C. But the machine still shut down. (At this point I was sure this is some other issue and not just the heatsink! But the service engineer said they just 'reapplied the thermal paste for better heat dissipation'). This solved the random shutdowns but I don't understand how. Anyway that's probably for another discussion).
4. I did another TM backup on an external USB hard drive and gave the machine for service.
5. I got back the Macbook and I tried to revive the old backups from NAS and probably merge with the latest one on external drive.
6. I tried to mount the sparsebundle image and kept getting the "no mountable file system" error.
6a. I'm not sure if the multiple unsuccessful backups corrupted the disk image somehow (although I don't understand why it would).
7. Then I tried to repair the disk image with Disk Utility but got the error "Disk Utility cannot repair this disk. Backup the disk () and restore files". I tried this multiple times and got the same error with almost the same scan time.
8. I tried to repair with Disk Warrior and it said Directory cannot be rebuilt due to disk hardware failue (-36, 2747).
8a. It's a disk image on a network drive so I don't get why Disk Warrior says it's a hardware failure!
9. I tried a sudo fsck and got this:
9a. XXXXs-MacBook-Air:~ YYYY$ sudo hdiutil attach ...... -nomount
/dev/disk1                    Apple_partition_scheme
/dev/disk1s1                  Apple_partition_map
/dev/disk1s2                  Apple_HFS
XXXXs-MacBook-Air:~ YYYY$ sudo fsck_hfs -f /dev/disk1s2
** /dev/rdisk1s2
   Executing fsck_hfs (version hfs-226.1.1).
** Checking Journaled HFS Plus volume.
   The volume name is Backup1
** Checking extents overflow file.
** Checking catalog file.
** Checking multi-linked files.
   Incorrect number of file hard links
** Checking catalog hierarchy.
** Checking extended attributes file.
** The volume Backup1 could not be verified completely.
9b. Disk Utility also gives the same file hard links error when I try to repair.
10. I'm still not able to mount the disk from sparsebundle image. But when I attach the image, the partition shows up in Disk Utility sidebar and is greyed out.
I think this is just some software issue with corrupted links or the like and not a hardware failure of the NAS.
I had a few thoughts to solve this:
a. Is this an encryption issue? Is there a way to decrypt the sparebundle image with a third party software? I know the encryption password.
(Lesson learnt. Never encrypt the backup unless you really need to).
b. Could it be an issue with the plist.info file or something? Maybe a modification to the file would fix this?
I'm not sure how to do this and I don't want to try any more things and risk losing the data. The size of the disk image is the same as before so I think all the data is still there. It's a few months worth of TM backup so I would really like to restore it.
I would greatly appreciate any help! Thanks!

Extremely unlikely.
It is possible to use Back to my Mac to back up to a Time Capsule over the Internet, but many folks can't get it to work; even when it does, it's very slow.
I've never seen any posts about it being done to any other Internet destination.

Best video format for converting DVD to NAS for widely sharing

Summary: The article shows you with an easy workaround for
copying DVD to NAS for streaming by ripping DVD to NAS friendly video
format on Mac and Windows
I recently purchased a NAS to store all my music/photos etc on. I
can stream stuff to my iPhone/iPad using the NAS software. What I want
to do is rip all my DVDs (over 400) to my NAS, but I’m not sure which
format to do it in, to play nice with my Apple TV2, Xbox 360, iPhone,
iPad etc. I wanna get some advice as to what format to rip in and what
software to use?
Learn some tips from online, I got know that to copy dozens of DVD movies to NAS,
you need to get the content off the DVD disc as a protection-free and
easily readable element for NAS. In this case, at the first place
powerful third-party software for backup DVD to NAS is what you need.
There are many, many DVD ripping tools on the market. I’ve tired a pile of them.
Brorsoft DVD Ripper
is the best one I’ve tried yet. It is capable of ripping DVD to MP4,
AVI, MKV for NAS streaming with no quality loss; it also enables you to
copy DVD main movies for backup onto NAS in .vob format. And what I’ve
learned is that MP4 would be one best target format for it is fully
compatible with nearly all media devices including iPad, iPhone, PS3,
Apple TV, etc. If you are running on Mac OS X, turn to DVD Ripper for Mac. If you haven’t got the software, download it now and let’s start the conversion.
Ripping and copying DVDs to NAS
1. Launch the DVD ripping program for NAS devices . Then
click "Load DVD" to import the DVD files you want to convert. To select
the subtitles you like, simply click Subtitle and select the one you
prefer. P.S. Before start the conversion, you can choose to backup DVD mian movies.
2. Click Format bar and choose your desired format. To store
hundreds of DVD's on NAS, you can rip DVD to .mp4, or .avi, .mkv, etc
compressed format. And click Settings bar, you can adjust the level of
compression to suit the quality you want.
Tip: If you like, you can click “Settings” to change the
video encoder, resolution, frame rate, etc. as you wish. Keep in mind
the file size and video quality is based more on bitrate than resolution
which means bitrate higher results in big file size, and lower visible
quality loss, and vice versa.
3. Press the "Convert" button to start ripping DVD for NAS streaming.
After the conversion, click Open button to find the output files.
Make sure the wireless network connection is accessible among the NAS
and Apple TV, PS3, HD TV or other media players. Then just enjoy the
high quality DVD movies anywhere anytime.

I've always found encoding with Handbrake and choosing the Apple TV2 preset is an excellent place to start and video encoded using that preset will work on my iPhone 4, 4S and iPad 2.
If the files encoded using that preset are too big for one's taste they can always encoded at a lower average bit rate rather than using the default 'Constant Quality' of 20.
Later on I'm sure the Handbrake group will have an AppleTV '3' preset supporting the 1080p format supported by the ATV3 and iPad '3' but using such a preset would not create a file usable on the iPad 2 or the iPhones.

Burn speed for iPhoto...?

Greetings,
A friend of mine had a Mac Pro 2x 2.66 Dual Xeon, 2 GB, running Mac OS X 10.4.11. He encountered a problem burning a DVD-R from iPhoto '08. He got a media error with a Sony DVD-R disc. He says he hasn't had any problems with his dual Pioneer DVR-111D drives (firmware AB09) and this media.
Is there any way to change the write speed for iPhoto '08?
TIA

Did he try another Sony disk? It might be just one disk.
Happy Holidays
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

I set up time capsule using a wireless 4g modem. it's been five hours and it still is saying making backup disk available (4.97 GB of 18.52 GB). Can I stop the whole thing, get a ethernet cable and start over to increase the speed of the backup?

I set up a new time capsule on a wireless 4g modem. I started the initial backup. It's been five hours and it still says "making backup disk available (4.97 GB of 18.52 GB)." Can I stop the whole thing, connect my computer to the time machine using an ethernet cable and start over to increase the speed of the backup?
Thanks,
David

oh i already did that. Im working on my imac and looking into this on my macbook. Was able to reproduce the issue again by trying to open TM. Locked out the finder again and had to restart. I checked the serial number and it was an early 2009 purchase with no coverage.
If you bought a Mac and got AppleCare with it, within 2 years of buying the TC, the TC is covered, too.
I have to admit that this $500 unit was the first to apparently junk out. The western digital that had my main data on that is my daily external that I store about 2TB of data on is still perfect and the new technology TM appears to already be cashed. Love the computers, not to big of a fan on the externals of the apple TV's. No life expectancy. Neither here nor there.
suggestions before I either get this looked at or scrap the HD on it and move forward.?
Reset the TC. See [Resetting an AirPort Base Station or Time Capsule FAQ|http://support.apple.com/kb/ht3728].
Try a "full reset" of Time Machine, per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
If all else fails, take it to your local Apple Store or Authorized Repair location, they may be able to determine whether the disk is dead.
If it is, they might replace the TC for you. If not, they won't repair it, but if the electronics are ok, you can replace the HD yourself, if you want to. See http://discussions.apple.com/thread.jspa?threadID=2542983

Cooling Fan ran full speed for no reason

iMac G5 17in 1 meg ram less than year old. Was sitting there in sleep mode and fan started running full speed for no reason. Computer screen black and would not wake up with keystroke. Shut down computer via rear panel switch and restart, all fine now. Do not understand why this happened but suspect it is actually a software problem, see below. Anyone have an idea so can understand what happened?
My iMac has the combo drive, not superdrive. I use an external 8x DVD burner for backups and iMovie. Yesterday I burned a iMovie (short) just fine. Then decided to back up my some of my Movie files along with iPhoto and iTunes media files. I tried three times but the burner did not work as usual. The first copy failed to verify and when I put it in the iMac slot, dumb I know, it did not show on the desktop. I restarted the computer to eject the disk, worked ok. The second copy did not work either, but did not put it in the iMac. The third copy burned but took a few hours to get 39% verified. I tried to stop the process with force quit, but it would not quit. Finally shut down the iMac via rear panel power button as a last resort as nothing on the desktop would respond to a mouse click. Computer restarted ok and worked fine for several hours until it went to sleep as I did last night.
I know using the power button is a last resort and possibly there is a keystroke that can force a proper shutdown. Also suspect the DVD external drive is balmy now, BenQ. But was amazed that the iMac still seemingly had some bug up its operating system this morning causing it to freeze and the fan to run full speed.
Again, any ideas...now be nice....I have tender ears
btw have three year warranty and just love the Mac, am going to sell my Dell laptop and get a PowerBook real soon.

Well the problem is fixed. I did call Apple Support and they ran me through the hardware utility. The problem I reported was that the system took forever to startup and that once the fan ran at full speed for no reason. I was not aware of the slow boot when I wrote this question so did not refer to it. But, after the DVD debacle my iMac would hang on the black screen just after the chime for about a minute or longer. The system worked fine once booted. This long boot came from both restart and a cold start. Think it happened once when I was trying to wake it from sleep yesterday, that is when I shut off the 'puter with the poer button. Anyway, the disk utility showed no problems
The Apple Careperson was very nice and stayed with me until the issue was resolved. It turnes out that unplugging my USB hub cured the slow bootup problem, and probably the fan.
So I am guessing that something in the external DVD hardware went and damaged the USB hub. It would be too odd for two devices to fail, on their own, at the same time.
The good news is that I just found a nice LaCie external DVD with firewire 400 support, so guess what I am buying.
As for the USB hub, well without the external DVD I don't need it right now so will wait to replace it.
Thanks for your help and I hope this may help someone else down the line.

Can the time capsule be used as both a time machine backup and NAS storage

Can the time capsule be used as both a time machine backup and NAS storage? I want to use the drive as external, wireless storage for all of my files so all my PCs, MACs and iOS devices can access the files. Plus, I want to use the drive for backing up my iMac via time machine. Can the time capsule device be used for both these purposes simultaneously? If not, are the other suggestions on how I can do this?

Can the time capsule device be used for both these purposes simultaneously?
It can, but is really not recommended. Sooner or later there will be a fight for space on the drive between Time Machine and the other files.
If you have plenty of free space on the drive, you can do this......but.....have you thought about how you will back up the "other" files that are stored on the Time Capsule?

E3000 Max Throughput for internet and USB NAS

I have been running some test to see what I can do for speed to the interenet and NAS drive.
I have a NIC card (1394) and the max connection I get is 400 Mbps. The card is suppose to be 10/100/1000 card and E3000 is the same... so why can't I connect at 1000?
Max transfer I get to my NAS is 64-80 Mbps. Is there any way I can get this to be faster? I have a 1TB western digital drive attached.
If I went with a NAS system like a Synology BYOD system could I get faster speeds for transfers if the NIC on the system was a 10/100/1000?
Thanks
Scott
Solved!
Go to Solution.

Most of the bottleneck comes from the processor, not the USB standard. Most NASs have a CPU with a clock speed higher than 1ghz which is dedicated to moving data to and from the hard drive. The E3000 on the other hand as a 480mhz processor which is used for multiple processes (e.g processing network traffic to and from various sources). I'm sure that you can already figure out what processes have a higher priority.
I don't work for Cisco. I'm just here to help.

What has happened to download speed for any video....tv, movies

Since about 2 days ago, the download speed for purchased video has become ridiculous. A 30 minute tv show takes MORE than 30 minutes to download......it used to take about 3 minutes...or less. I rented TRON yesterday and it took over 3 hours to download......it used to take 10-15 minutes. This happens on both my 2 Macs and 1 Windows machines. My Internet connections report a solid 20MB down and 1.5 up.....on every machine and device I have. It is NOT a problem in my home system or machines. All other downloads are fine.
Something is seriously wrong with Apple's iTunes websites. I am certain that there is nothing wrong locally......no machines have changed.....and they all experience this abysmally slow service.
Netflix streams full HD fine on all machines, by the way. I wouldn't even begin to download an HD movie from iTunes until someone at Apple figures out why their service suddenly is not useable.

My box has similar issues with Multiplex D (which Film 4 and 4 Music are on). My TV is absolutely fine but my Vision box is less happy. I have the channels listed but no picture. I keep meaning to replace my aerial leads but haven't got round to it. Strange thing though is that my aerial goes to my vision box which then goes to my TV so it makes no sense as I would expect the reception to be the same or worse on the TV as with the Vison box.

DAG - Backup failing on 1 DB only with error - The Microsoft Exchange Replication service VSS Writer instance ID failed with error code 80070020 when preparing for a backup of database 'DB012'

Hi Board,
i´ve search across the board, technet and symantec sites but did not found a hint about my problem.
we drive a 2 node DAG (Location1-Ex1-mb1
Location2-exc1-mb1), on SP2 RU4 patchlevel with 40 Databases.
Since some time the backup of one - and only one DB - is failing with these events, logged on the Mailboxserver on which the passive DB is hosted.

to restart the MS Exchange Replication Service – BUT the mentioned eventID

The affected Database is active on Location2-Exc1-Mb1 Server and in an overall healthy state. I found during my research, that below Location2-Exc1-Mb1 Server, there are not removed shadow copies present!
This confuses me, since all Backups are normally taken from the passive copy of a Database.
So my questions to the board are:
* Does anyone is facing similar issues?
* Can someone explain why snapshots are present on the Mailboxserver hosting the Active Database, whilst the errors are logged on the passive one?
-          * Does someone know the conditions, why shadows copies remain and
aren´t removed in a proper manner?
What can cause the circumstance, that only 1 DB is facing such issues?
Any suggestion is welcome!

Hi Lenora,
I´ve encreases VSS / Exchange Backup Log levels to expert, before starting
those things i´ve all tried now:
- Backup from passive DB (forced within Symantec Backup Exec)
- Backup from active DB (forced within Symantec Backup Exec)
- Backup from passive DB without GRT enabled (forced within Symantec Backup Exec)
- Backup from active DB without GRT enabled(forced within Symantec Backup Exec)
All those attempts failed.
But brought some more details - the backup against the active DB states, that there is still a backup in progress and therefore this backup is cancelled by VSS.
The Solution was, that i´ve needed to restart the Exchange Replication Service on the Mailbox Server hosting the passive DB.
Backups are working again on all DBs!
THX for your replys.
Best regards
Markus

Password for encrypted backup of device

I need help to change the type of encryption for my iPhone and iPad backups in itunes. I have tried all the passwords I ve used in years and have no clue. Somewhere in Support I found an instruction that did not lead to clearing the password. It did send me to backup to iCloud and do a restoere from there. But this is not what I am trying to acheive. I already was backing up to iCloud. If I need to do a restore from a backup in iTunes on my PC I cannot do it because I cannot provide a correct passowrd for the encrypted backup.
Can anyone help me with a solution?

If the user cannot remember the password for the backup, the backup is useless. There is no way to reset or remove the password requirement.
If the user did not enable backup encryption, the backup is corrupt.
In other words, the backup is no good without the password, delete it and move on with life.

How to restrict disk space when using time machine for client backup on server?

We have 10 OS X SL Clients backing up on xserve SL with TM. Now 1 TB disk space is used and disk is full. The clients get the massage that the latest backup could not be finished due to target disk full. Clients run just OS X Standard Software plus Parallels with windows (max. 50 GB per client)
Why does TM not delete oldest backups like with external USB HD?
How can we restrict disk space on server to eg. 750 GB for total backup space for all clients?

johndave, did anyone ever respond to your post?

I am trying to restore a backup onto my iphone from itunes but it asked me for a backup password which I cant remember, is there anyway that I can reset the password and not lose my backup?
