Trouble reading files, error -523 (service transaction error).

This occurs on just 3 out of 24 mailboxes and in all instances, in the log, it's accompanied by the line:

T-14: PtSend: cmd MbeF/msg RdBg: byte count XXXX exceeds maximum of 1024

Configuration as follows:
Backup server: Win 2k, Retrospect 7.5.508 with Exchange Server add-on, + hotfix 7.5.14.102.

Exchange running on a seperate server: Win 2003 SBS, Retrospect client 7.5.116

Does anyone know what the problem is here and how to sort it? ]]>Wed, 18 Jun 2008 10:38:37 GMThttp://forums.dantz.com/showtopic.php?tid/27393/http://forums.dantz.com/showtopic.php?tid/27393/
Windows server 2003 with Retrospect 7.5.508, driver pack 7.5.14.102. Connected via gigE/iSCSI to a Spectra Logic T50 w/ LTO4 drives.

Whenever I try recovering an exchange snapshot or mailbox files, Retrospect/windows attempts to recover files (and sometimes succeeds), but the library always falls off the iSCSI buss, neither retrospect nor windows sees it any more. I generally have to POR the library to get it to be useable again. Oddly enough, the tape drives usually remain connected and useable, it's just hard to change tapes when the library won't talk to you... Although they too have occasionally disappeared as well.

This problem does not occur with other types of data, be it large movies from a media server, or system files from the exchange server, just the snap shots and the mailbox files. It is reliably reproducible.

I've been working with support at Spectra Logic, and we're wondering if Retrospect does anything different (scsi command wise) with Exchange Backups than it does with other file based backups, or if there is anything else that we might be encountering that anyone has heard of.

Any ideas what's up?

Thanks!

The server is a Windows 2003 Standard edition server (not a domain controller), 4GB RAM, Exchange Server 2003, using Retrospect 7.5.xxx (I'm not connected to the server right now, but the latest updates have been applied) with the Exchange Agent. It is backing up to a hard disk more than large enough for the backup.

Here is an excerpt of the log (user names have been edited):

As you can tell by the initials of the users, these accounts are in the middle of the run...

You can disregard the -3405 error, I just read another post on how to clear that one up...

Thanks in advance.

Needless to say, I'm not backing up exchange with retrospect ever again. For the moment it's NTBackup and exmerge. We're evaluating our other options.

I'm new to backing up Exchange, and want to know what the best strategy is for backing up Exchange data to tape.

I have Monday through Thursday tapes. Each runs a Normal backup on its day for 4 weeks, then gets a Recycle backup and starts over. I have Friday sets that run Normal backups each Friday, and get new media every month.

I'm running Exchange 2007 on Win2003 server, with the latest Retrospect running on a separate backup server. I have been backing up "Exchange Server", not "Exchange Mailboxes".

I'm a little nervous about incremental or differential backups with Exchange, so I have chosen "Full Backup" under the Exchange Server options in retrospect, and these run every night to the daily tapes. At this point, I'm using up too much tape space with this method, so I'm thinking of changing to "Differential" or "Log/Incremental Backup".

First, can I trust Differentials or Incrementals to back up Exchange reliably? (I do my files that way, but a large monolithic database??)

Second, which method, "Differential" or "Log/Incremental Backup"? (I'm not quite sure what each implies...)

Thanks for the input...

T-10: PtSend: cmd MbeF/msg RdBg: byte count 1079 exceeds maximum of 1024
Trouble reading files, error -523 (service transaction error)

When the error initially occured I tried upgrading Retrospect to the newest version which is now as follows.

We are now using Retrospect Multi Server Version 7.5.508 with Driver Update and Hot Fix version 7.5.14.102.

One thought I had was a possible corrupt email in both mail boxes. However I have been able to successfully open all emails that were received between the last successful backup and when it started. I'm also able to use Ex-Merge to export both mailboxes successfully to a pst file.

I also have 50 other mailboxes on the mail server which are still being backed up successfully.

I have seen a couple of other people mention an eror like this, but none of the topics seems to address the problem with a solution.

Any help would be appreciated. ]]>Wed, 23 Apr 2008 04:09:46 GMThttp://forums.dantz.com/showtopic.php?tid/27138/http://forums.dantz.com/showtopic.php?tid/27138/ ]]>Mon, 21 Apr 2008 16:13:40 GMThttp://forums.dantz.com/showtopic.php?tid/27132/http://forums.dantz.com/showtopic.php?tid/27132/ ]]>Sun, 20 Apr 2008 12:29:13 GMThttp://forums.dantz.com/showtopic.php?tid/27129/http://forums.dantz.com/showtopic.php?tid/27129/ public folders settings, integration settings to ActiveDirectory and etc., or it backs up only storage database components? ]]>Sat, 19 Apr 2008 14:45:25 GMThttp://forums.dantz.com/showtopic.php?tid/26911/http://forums.dantz.com/showtopic.php?tid/26911/
I am backing up the First Storage Group as well as individual mailboxes every Friday night using a Full backup.

Then every other night I have a script to run a Differential on the same sources.

Both of these scripts are set to go to the same destination Backup Set on a TeraStation Pro NAS.

Everything works EXCEPT for the differencial of the First Storage Group. It is giving me the following error:

Backup type: Differential
T-10: >>>HrESEBackupSetup(0c8000230) -- The database missed a previous full backup before the incremental backup.
Trouble reading files, error -3712 (The database missed a previous full backup before the incremental backup)

All of the remaining individual mailboxes backup just fine in the differencial script.

We are on Multi Server v7.5.508 and the exchange server has client version 7.5.116

Any suggestions???

Thanks,

i'm sorry for my short answer.

Here my problem (I hope my english is good enough):

Retrospect Version 7.0.344 Multi Server NFR with the Retrospect-Update, Version 7.0.12.105.

Retrospect is runnig on an Windows 2003 Server, our MS Exchange Server 2003 is running on another server. When retrospect backup certain mailboxes we get these 2 error messages:

T-2.067: PtSend: cmd MbrF/msg RdBg: byte count 1261 exceeds maximum of 1024
Trouble rreading files, error -523 (service transaction error)

and

T-2.067: PtSend: cmd MbrF/msg RdBg: byte count 1267 exceeds maximum of 1024
Trouble rreading files, error -523 (service transaction error)

In the past we've never had this problem. Another problem is, that one of the mailboxes is from my boss.

Do you have any idea?
Thanks
