NTbackup fail on one file only

[Guest T_A_C]

I've been using NTbackup for a couple years now, as follows: File server

(which has the VS80 tape drive, backs itself and also the backup files from

the Exchange server, nightly. The Exchange server backs up the Ex storage

group to a file and the systems state to a file, then the file server pulls

those two files down to tape each night. This process has worked flawlessly

until lately.

 

Now I get the message in my NTbackup logs as follows:

 

Backup started on 1/10/2008 at 12:03 AM.

WARNING: Portions of "\Exchange.bkf" cannot be read. The backed up data is

corrupt or incomplete.

This file will not restore correctly.

Backup completed on 1/10/2008 at 2:44 AM.

Directories: 1

Files: 2

Corrupt: 1

Bytes: 43,685,847,664

Time: 2 hours, 41 minutes, and 41 seconds

 

I verified that the NTbackup on the Exchange server is working with NO

errors, so the Exchanged.bkf is a good file! however when the file server

pulls it down to tape the log spits this error out. All other files (local

and remote) gets backed up successfully (and verified), with the exception of

the Exchange.bkf.

 

I have Acronis making an image of the file server (vss enabled), nightly...

however they are done at separate times (Acronis is done by 10:30pm, NTbackup

starts at 12 midnight).

 

I've deleted the existing Exchange file... (made no difference), made sure

my imaging is not timed at same time... the Exchange.bfk is approx 43GB's in

size.... at this point IM STUMPED!!??!

correction VS160 drive, and the exchange file is the first file to be backed

up, all other files backup successfully afterwards.

Maybe the process that generates the .bkf file hasn't finished

by the time you're trying to pull it to tape. Have a look at the

details in the corresponding backup log!

Re: NTbackup fail on one file only

 

the backup verification on the Exchange server finishes at approx. 11:11pm,

the file server doesn't access the bkf file until 11:55pm

Re: NTbackup fail on one file only

 

I did put all the servers on the same (new) switch the same day this

started... I'll enable jumbo frames on it... perhaps that will make the

difference since the files is 43GB+...???
