Can anybody explain the QubesOS backup file naming convention, please?
I think it is qubes + vm name where the backup was created + date + SOMETHING
Could you post an example filename? I don’t have one handy.
The “SOMETHING” is probably (part of) the timestamp.
I don’t know for sure but from my observation, backup files that are created from the GUI (Qubes Manager > Backup Qubes) seem to be named as follows:
qubes-backup-yyyy-mm-ddTHHMMSS
with:
yyyy
being the 4-digit year, e.g. 2021,mm
being the 2-digit month, e.g. 02,dd
being the 2-digit day, e.g. 13,HH
being the 2-digit hour, e.g. 10,MM
being the 2-digit minute, e.g. 35,SS
being the 2-digit second, e.g. 55
After all, it may be possible, that this depends on the time zone settings (regarding 12h/24h format).
The name of the qube is not stored in the backup name - that would leak information.
The date and time are taken from the system where the backup is made -
if you manually set the date back a year, the backup file will be named
using that date: plenty of scope for obfuscation here.
Backup naming uses 24hr format.
Thanks.
