Module export 

A volume backup’s run, for crate::backup: hook, snapshot, a temporary volume copied from the snapshot, incus’ export of it (uncompressed tar) compressed and streamed to the bucket, then the temporary volume, the export and the snapshot deleted.

The snapshot is what makes it consistent: the export is of a volume nothing writes to, taken right after the hook. incus writes its export to its own backups directory on the host while it is read; that copy goes when the run ends (and incus expires it after a day if isb could not).

Functions

backup_once

One volume backup: export, upload, verify, prune.

check_source

What a volume backup’s source must be: a volume in the org.

files
