|
The `backup` command by default selected the parent snapshot based on the hostname
|
|
|
|
|
and the backup targets. When the backup path list changed, the `backup` command
|
2022-12-10 16:02:29 +01:00
|
|
|
was unable to determine a suitable parent snapshot and had to read all
|
|
|
|
|
files again.
|
|
|
|

|
|
|
The new `--group-by` option for the `backup` command allows filtering snapshots
|
2022-12-10 16:02:29 +01:00
|
|
|
for the parent selection by `host`, `paths` and `tags`. It defaults to
|
|
|
|
|
`host,paths` which selects the latest snapshot with hostname and paths matching
|
2023-07-27 21:52:04 +02:00
|
|
|
those of the backup run. This matches the behavior of prior restic versions.
|
|
|
|
|
The `--group-by` option should be set to the same value as passed to
|
|
|
|
|
`forget --group-by`.
