Hi,

after I've a restart of an VM or the Hyperviser, the dirty bitmaps are gone and the backup took a longer time?

I'm not realy shure about this behavior.

Bye

Yes, that's how dirty-bitmaps currently work. They're only kept in RAM, so as soon as a VM stops they are lost.

We are looking into keeping dirty-bitmaps alive during migration and move_disk events, and at some point maybe even persisting them to disk.
