Implement basic volume backup and restore mechanism This commit implements three new services, specifically: - The `container-volume` service, which applies to a specific volume name and ensures this exists. This is mainly useful as a dependency to other services, as Podman will create named volumes itself if needed. - The `container-volume-backup` service, which creates a `tar.gz` snapshot of the given volume's contents in `/var/lib/backups`. - The `container-volume-restore` service, which populates an empty volume from a pre-existing file in `/var/lib/backups`, presumably created by `container-volume-backup`. These are then be used to automatically create volume snapshots every 12 hours, rolling over every 7 days. 2021-08-14 21:31:02 +00:00			`[Unit]`
