Symantec Backup Exec 12.5 not backing up correctly...

[R.O.S.S.I]

Can anyone help me out with a problem im having with our Symantec backup?

Basically we have a nightly backup set up to run at 10pm every night, backing up our main server, exchange, and Citrix to tape.

Everything has been working fine and dandy until Thurs last week when it didnt backup saying

"e000fe29 - Authentication failed on connection to the server. Make sure that the user account has the appropriate permissions and that the password was typed correctly.
For additional information regarding this error refer to link V-79-57344-65065"

Now i've referred to the link and followed the steps in it to rectify the situation but it still does the same. The first 2 times it failed without backing up any data, now it keeps failing around the 90GB mark and has done for the past 3 evenings.

I've checked that the admin AD account pass is still the same as it always was, and also checked this against the network logon account in Backup Exec which is fine but its still erroring doing the backup.

It's not a tape issue as we switch tapes every night and this has happened on 4-5 different tapes now.

Does anyone know what could be causing this?!

Tried rebooting all the servers and restarting the services too but it still error'd!

Pain in the bum this is! When it works its fine, and we rarely have problems with it, but it appears to be when a problem does occur its a nightmare!

Is 90GB about the total? It marks jobs as failed if it can't backup a single file so have a look in the logs.

No, the full backup is around 240GB.

this mite sound retarded but has the dates or times been messed with, Ive had silly issues with backup exec when ppl change this in windows or even the bios date and time.

Not as far as I can tell, everything appears to be set correct in Windows. The BIOS time will have most certainly not been changed.

Have a look at the job log to see at which server/file/folder it is getting stuck on.

It may be wise to split the job up into three separate jobs purely to trouble shoot. Or alternatively change the resource order.

I'll have a check through, i'm not quite au fait with Backup Exec yet so will have to do some reading on how to get the logs etc.
