Netbackup accelerator full backup fails

Hello all,

I have Netbackup accelerator backups of Windows 2008 file server which fails when performing full schedules. Master server is 7.5, MSDP is 7.5.0.7, client server was 7.5.0.4, I installed 7.5.0.7 client patch but it did not resolve the issue. I have change journal enabled on client.

The problem is that I can perform the first full backup (I tried to completely uninstall Netbackup client), I can then perform incremental ones with accelerator, but next full backups with accelerator and with accelerator forced rescan fail.

These backups are either pending after the buffer size limit is reached and I`m  forced to kill bpbrm on media server to cancel the job  or they fail with errors that you can see in the log below (please do not look at E: drive, actually it was a redundant selection, I only backup DSmiley Happy

Today I tried once again to completely uninstall the client and I ensured the Install:\Veritas folder and  VxCJDelete.dat. VxCJInfo.dat and VxCJMon.dat files are removed. I removed the client from policy and added it again. I have just started the full backup but I can see that activity monitor is still able to calculate the estimated backup size --> how is it possible if no track file exist? In the past removing track files resolved my accelerator issues but in this case I`m afraid it will not work...

This is really strange, after complete client uninstall my first backup is behaving as if it were still using the journal files....One more detail, the legacy settings were True Image Restore with Move detection and accelerator, when the issue appeared I disabled TIR, as I understand it is not recommended to have both TIR and accelerator. I have Keep TIR restore info set for 14 days on master server. Is it possible that this is still causing the problem?Is it the reason why estimated backup size is displayed in activity monitor?

I ensured that McAffee settings on client follow meticulously the Symantec recommended (journal file excluded from scan etc.) Also in the past applying these AV settings solved my acclerator issues but not this time.

We didn't get stable

We didn't get stable accelerator backups until 7.6.0.2, and both the client and server had to updated.

Hello, thank you for this

Hello, thank you for this answer, I`m sorry I did not reply earlier, I was busy on antother projects, it is only now that I came back to the issue. My general impression from several discussions I read is also that accelerator in 7.5 is s unstable. I will try my last chance and open a call with support and either upgrade or resign from accelerator. Menawhile I`m thinking to suggest performing only incremental backups. I wonder what might be the impact of running only inc accelerator backups, apart from the fact that they might take longer time?

Re: Netbackup accelerator full backup fails

It's suggested to upgrade your master to 7507.

If I remember correctly, there is size limitation with track log, so if you only launch inc accl backup, the backup id of every backup will be recorded in track log, which might cause track log crash. Usually hope that having full and inc schedule together, after every full accl backup, just only this backup id will be recorded in track log, all the previous backup ids will be removed. so you can avoid the track log issue.
