Arcserve "pre_backup.pl" script doesn't make a snapshot on ESX 3.0.1

Has anybody successfully restored an ESX 3.0.1 VM backed up by the Arcserve 11.5 Linux agent (i.e. agent installed in the Service Console)?

I configured everything per CA's VMware Best Practice Guide, and the helpful posts on this forum. The resulting backup jobs get everything except the active delta & vswp files. However, the CA_SNAP file referenced in the CA doc doesn't get created, and when I delete the vm from the datastore and restore it from backup, the vm can't start.

AHA! I tracked down fix QO82899 on the CA supportconnect website. It contains an updated version of the pre_backup.pl script which DOES create CA_SNAP.

I'm running a backup now, when it's finished I'll delete the VM and start a restore tonight. We'll see how it turns out tomorrow, my last restore took 7 hours (see other posts about slow restores to vmfs volumes).

Nope, it's still broken. The backup and restore jobs both ran with no errors in Arcserve, and I can re-register the restored VM, but when I try to start it up, it throws this error (which I think is a red herring) about 20 times:

"This CPU is VT-capable, but VT is not enabled (check your BIOS settings)."

Then it gets to what is presumably the real problem:

"VMware ESX server cannot find the virtual disk '/vmfs/volumes/000002-vmdk' or one of the snapshot disks it depends on.

Reason: The system cannot find the file specified."

When I browse the datastore, the vmdk file and all the snapshot files are there. Any ideas?

Edit the vmx configuration file, and look the path to your vmdk file.

Show also the vmdk file.

How do I edit the vmx file? Can I just open it in vi from the ESX service console?

OK, that worked. I pointed the config at the earlier -00001.vmdk file, and now it boots.

The previous snapshots are all gone from the snapshot manager, even though the vmsn files are still in the datastore. Not a huge problem, but it'd be nice to have them back too.

Any suggestions on how to retrieve the snapshots? Extra credit available Smiley Wink
