What i currently not get is the difference between:
1) create a snapshot and bitmap in an transaction OR
2) create only a bitmap and then use the drive-backup
with sync=full to create a full backup, like shown in the
examples.
using the snapshot i can be sure my disk is not changed during
backup as the backing file of the snapshot gets written and
changes get commited back as i remove the snapshot, or does
drive-backup take care about this too? Does it even make
sense to create a full backup using a snapshot or should
i only use the bitmap and drive-backup feature?
As i understand based on wether i use 1) or 2) i get
the different behavior regards backing files as you
describe and must use different ways to recover.

yes, only testing here to get an understanding how it works.
thank you,
