I only do automated copy
to B2 from the local archive, no automated sync
, which as far as I understand should be non-destructive with versioning enabled.
If I need to prune, etc. I run will manually sync and then immediately restic check --read-data
from a fast VPS to verify B2 version afterwards.
Not actually used it. I started off doing local backups, B2 was an add-on way later down the road.
