'Sparsebak'

Fast Time Machine-like disk image backups for Qubes OS and Linux LVM.

I tested the new version this morning and had worked around a few issues such as first trying to run from /usr/local/sparsebak, and then went back to square one and used /sparsebak as it was originally intended.

$ sudo /sparsebak/sparsebak.py send --save-to sys-usb:/run/media/user/USBdrive/sparsebak

I was attempting to "send" all my VM's private sections to a drive mounted on sys-usb, and I seem to have run into a problem with one particular AppVM. When it got to my vm-vault-private it printed:

"Delta map not finalized for vm-vault-private ...recovering."

and a few seconds later this exception:

"
Processing Volume : vm-vault-private
Updating block change map: Traceback (most recent call last):
   File "/sparsebak/sparsebak.py", line 1008, in <module>
      monitor_send(options.volumes, monitor_only=False)
   File "/sparsebak/sparsebak.py", line 543, in monitor_send
      = update_delta_digest()
   File "/sparsebak/sparsebak.py", line 307, in update_delta_digest
assert bkchunksize >= (bs*dblocksize) and bkchunksize % (bs*dblocksize) == 0
AssertionError
"

All the other AppVM's appeared to be processed/snapshot'ed Ok, but since there was this one fatal exception the backup obviously did not complete. I'm not sure what the complaint is with the blocksize because the AppVM runs fine and with no errors that I can see.
