Enhancement: (alpha) Store deviceID only for hardlinks
|
|
|
|
Set `RESTIC_FEATURES=device-id-for-hardlinks` to enable this alpha feature.
|
|
The feature flag will be removed after repository format version 3 becomes
|
|
available or be replaced with a different solution.
|
|
|
|
When creating backups from a filesystem snapshot, for example created using
|
|
btrfs subvolumes, the deviceID of the filesystem changes compared to previous
|
|
snapshots. This prevented restic from deduplicating the directory metadata of
|
|
a snapshot.
|
|
|
|
When this alpha feature is enabled, then the deviceID is only stored for
|
|
hardlinks. This significantly reduces the metadata duplication for most
|
|
backups.
