I have a question relating to our tape backups
Im running Veeam 126.96.36.1995 on Windows 2012 R2 on a physical server with a FC connected HP 2024 LTO6x2 library.
I have been running reverse incrementals for well over a year now without any issues. These jobs create Per-VM backups in respective repositories.
I have the disk jobs configured to process our VMs in order of size, largest first.
I have tape jobs running which are configured to write "Backup jobs" (not repository or files) to tape daily once the disk reverse incremental are complete.
This is configured for Fulls, not incrementals. These have also been running without issue, until last night when the job failed at around 80% asking for another tape.
There have been no changes to the backup jobs, or VMs being backed up, and there has been no noticeable growth for the VMs being backed up.
When I investigated the space remaining on the tapes, there is well over 500GB free on each tape still however the jobs would not progress. The media pool used is configured for Parallel processing of jobs using 2 heads, as well as parallel processing of chains within a single job.
I can see no reason why this job has failed as there is ample capacity on the tapes, these jobs have not grown or changed, and the jobs have been completing without incident for several months now.
Can anyone shed any light?
