Backup completed with exception

Is there something special about these paths? For example, are they located in a mount point, on a SAN disk, etc.?

Does the SYSTEM account have the Full Control permission for these files? What user account is avtar running under?

Avatar is running local system account and the permission to Read and Write permission is set for Everyone , also one more thing those folders are in Clustered .

But if at the time of backup if these folders are present on different servers than I doubt it will show that error

If these are cluster resources, it sounds like you the cluster backups may not have been configured according to best practice.

When backing up a cluster, you should have a minimum of three avagents running:

1. The avagent on physical node 1 (let's call this host cluster-p1)
2. The avagent on physical node 2 (let's call this host cluster-p2)
3. The avagent for the virtual cluster node (let's call this cluster-v1)

There should be one additional avagent running for each additional physical or virtual node in the cluster.

We'll further assume that each physical node has a system disk (C) and some local storage (D). The virtual node will have two cluster volumes (E and F) plus the quorum drive (Q which should never be backed up).

The cluster should be configured so that each of the physical nodes back up only local resources (in other words any resources that are not part of the cluster). The cluster volumes (and only the cluster volumes) should be backed up by the virtual node. The datasets would look like this:

cluster-p1

• C
• D

cluster-p2

• C
• D

cluster-v1

• E
• F

Hope this helps.

Hi Ian ,

These are not the SAN Disk or mout point ..its a Basic Disk Directly attched to server but these are the shared folders .

It looks like there may be some filesystem inconsistency on the target volume:

I would recommend examining the System and Application event logs around this time (2012-07-09 01:00:43) to see if there are any errors or warnings reported. This I/O error is being returned to us by the Operating System which implies some kind of issue outside of Avamar's control.

Hi Ian ,

Sorry for the confusion the E:\ drive is not a clustered drive but the Application team is using a script which copy some of the folders from one server to another server and vice versa.

Also all these folders are the Shared folder in which the permission is set to Read \ Write o everyone , attaching logs also

It looks like the VSS snapshot is deleted while performing the backup, check the event logs and see if you have event 35 or 13 . There might be some Volsnap error...

Refer this article....

Hi Amol,

Is there any way in the AVAMAR so that we can disable the Snapshot and it will directly take the backup without creating the Snapshot first , as I can check the time whenever the Volsnap error shows in my Eventvwr same time those files are getting skipped in my backup log also if I have to take the backup of a drive having almost 600 GB of data contains millions of File how much disk space it required for the snapshot.

regards

Rohit

Rohit,

VSS shadowcopies are Copy-on-Write technology using Microsoft System Provider; by default the saved writes can occupy up to 15% of the size of the disk, and this can be set in LDM.

Yes, there is a way to disable VSS snapshot but it will cause backup to complete with exception on those files which are currently being access by user/application.

If you want to disable VSS snapshot for a particular client, Create a file "avtar.cmd" in the var directory of avamar client installation (Default c:\program files\avs\var) and add below lines in that file

--freezemethod=none

Hi Geeks

I have the same problem regarding my backup issue <5737>: I/O error: Unable to read(3) "  "C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\X-X-I-WEB02-20141106-2305.log"

avtar Error <5137>: Unable to open

need your kind advice and suggestions to resolve this issue.

Thanks in advance.

What could be the problem if we see similar error on AIX:

2015-03-27 03:01:29 avtar Error <5137>: Unable to open "/home/ldapdb2/NODE0000/SQL00001/SQLT0000.0/abcdef.DAT" for backup (code 22: Invalid argument). (Log #1)

looks like db2 database directory structure. Database is always writing to redo logs, database files and occasionally archive logs. You need to exclude that directory and if db2 database backup directory is required you need to use Avamar AIX DB2 plugin.
