[Unit]
Description=Backup {{ item.name }} using restic
[v2] feat: lvm: Add lvm-based backup functionality This commit implements the needs of #75[^1]: it allows for the creation of atomic backups when the backup target is a file/dir whose fs rests on LVM. This ensures the snapshot will be atomic. By using a mount namespace, the LVM snapshot can be done in the same directory -- so existing LVM-based applications of ansible_role_restic can be migrated to this implementation without any discontinuity in what appears to be backed up. This combination of LVM's snapshotting layer and mount namespaces comes with some caveats: - you cannot backup / due to namespace issues - subdirs with a separate fs won't be correctly detected - not all filesystems are happy about LVM snapshots -- btrfs, e.g. - LVM snapshots come with a performance penalty when active - fstrim and LVM snapshots don't like each other whatsoever [^1]: https://github.com/roles-ansible/ansible_role_restic/issues/75 -- Changes in v2: - Use `findmnt -v` to find snapshot when cleaning up - Check for _snap before `lvremove -y` Signed-off-by: Martin Kennedy <hurricos@gmail.com>
