files_snapshots

Access filesystem snapshots from Nextcloud.

Allows using filesystem snapshots (such as provided by zfs and btrfs) instead of builtin Nextcloud versions.

Limitations

This app does not automatically create snapshots itself, because of this it might not have a snapshot for every change made to the file.

Since no snapshots are created by the app, when reverting a file, any change made to a file since the last snapshot will be lost.

Configuring

In order to access snapshots, two things need to be configured under the admin settings.

• snapshot format: where the snapshots of the Nextcloud data directory can be found

  example: /srv/http/.zfs/snapshot/%snapshot%/nextcloud/data/
  where /srv/http/nextcloud/data is the Nextcloud data directory
  and /srv/http is a folder which is being snapshoted to /srv/http/.zfs/snapshot.

  Additionally, if your snapshots are organized over multiple directories like

  /.snapshots/hourly/2020-02-07_00:00/...
  /.snapshots/hourly/2020-02-07_01:00/...
  /.snapshots/daily/2020-02-06_00:00/...
  /.snapshots/daily/2020-02-07_00:00/...

  you can use a glob such as /.snapshots/*/%snapshot%/ to make the app search for snapshots in multiple directories.

• snapshot folder date format: How the snapshot date is formatted in the snapshot name

  Specifications about the format: http://php.net/manual/de/datetime.createfromformat.php

  Example: *Y-m-d_H:i:s* will correctly match snapshots named autosnap_2017-05-27_00:00:01_hourly

  Hint: Each * will only match until the next separator or digit

  Example: *-*-*-Y-m-d-Hi will correctly match snapshots named zfs-auto-snap_frequent-2017-06-23-1930
