dirty-bitmap and two jobs

[mgabriel]

Hi,

after the first backup, the dirty-bitmap is created and used for subsequential backups. the dirty-bitmap gets reset when a new backup is started.

I wonder what happens if a VM is backed up in two different jobs to different backup targets, first to pbs and second to a local rdx drive.

If the dirty-bitmap gets reset with every job, then every second backup to the pbs won't contain all changed blocks but just the blocks that changed after the vzdump to the local rdx.

Kind regards,
Marco

regular (VMA) vzdump backups neither use nor affect the dirty bitmap used by PBS backups.

So my outlined case above works, at least if only one job targets a pbs.

Thanks!
