Which is the cause of the message "data unavailable on server"?

[joluinfante]

I'm doing my virtual backups using the dsmc command.
I'm driving different retention periods for different types of virtual.
One day, I received a lot of messages "ANS4174E Full VM backup of VMware Virtual Machine 'xxxx' failed with RC = 14 mode = Incremental Forever - Incremental"
After seeing the suggested actions (where it is assumed that I had, for some unknown reason, failure mechanism cbt, by vmware), I decided to make a full incremental below the last.
After that, in certain virtual, I could continue to make incremental backups, but in other, higher retention, I keep getting the message.
The full backup was done correctly, and I can verify, with dsmc query.
I am using (my environment is linux), these variables in dsm.sys:


VMMC RMVMCFG_MC * 14 days of retention
include.vm myvm RMVMDAT_MC * 60 days of retention

Precisely, making backup "myvm" which has extended retention, it is where it fails.
Activate the trace during the backup, and receive these messages:

Any ideas?

My local support give the solution:
He do a "q actlog", see a error message with a .bfs file, repair it, and, my backups are working ok, again!

You got it - as part of incremental vmware backups, a small amount of control information must be restored from the server before the backup can start. If this data is unavailable for one reason or another (in this case some server-side problem), then the data can't be restored, and the backup can't complete.
