After migrating to new Server with Windows Server 2008 backup jobs became more quickly but only for one time.
after investigation, I found that during job between resources such as disk "C" "D" "System state" "Shadow Copy Components" from same server, it make PAUSES...
not a pause between jobs or etc.. pauses inside job.
Do some one know where the problem is?
Previous weekends were not such delay inside job.
Also no errors or any information regarding backup in System Event log
Look for delay between backup completes and starts
for Disk "D"
Backup started on 12/7/2012 at 10:15:33 PM.
Backup completed on 12/8/2012 at 5:01:47 AM.
for Disk "C"
Delay from 5.01.47 AM till 8.12.55 AM
Backup started on 12/8/2012 at 8:12:55 AM.
Backup completed on 12/8/2012 at 8:32:12 AM.
Shadow Copy Components
Delay from 8.32.12 AM till 11.35.53 AM

|Job Operation - Backup|
and some more information from same server but from another job
Look at Job started time
Job server: Job name: All - in - one-All-in-one Weekly- - profiles Job started: Saturday, December 08, 2012 at 12:09:47 AM Job type: Backup
Look at Backup started time
|Server - *********|
AOFO: Started for resource: "D:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS). The snapshot provider used by VSS for volume D: - Microsoft Software Shadow Copy provider 1.0 (Version 22.214.171.124).
to Tape library ibm3100 with 2 drives LTO5
in that time period there was active job for second drive but there weren't any conflicts between drives.
as I can see, previous backup was without any delay and there weren't any changes made in jobs etc..
I would like to push this as we have the same problem with BE2012 (fully patched) in a reeeeeeeally small environment.
Backup 80gb to tape takes around 1Day and 15hours because there is a large gap between ressource 1 and ressource 2. The tape and the drive are ok.
What is causing this?
...Connect is a best-effort, community-based forum that just happens to have some Symantec engineers trawling the forums as well. If nobody has contacted you, then you should revert to logging an official call with Symantec to resolve the issue.
With no further engagement from any forumites either, you should assume nobody has an answer which might now be resolved by logging an official query.
If you do get a solution, please post back here with the details.
We had a problem with backup times after a power cut. Resetting the backup drive and drivers fix the problem but there was still a speed issue where a pause/gap happened between jobs causing the total backup time to double. After opeing the job and selection lists, making a small change and saving, the job reverted back to their previous speed.
I am not aware that anything liek this has been offically reported to us and as craigV has already said the user community has nto been able to comment, then you shoudl resally log a formal support case for us to look into it.
However as a test - what happens if you backup the same servers to a disk storage device ?
