Restoring from backup

Restoring from a snapshot

Restoring a snapshot is as easy as it sounds, just use the following command to restore the contents of the latest snapshot to /tmp/restore-work:

$ restic -r /srv/restic-repo restore 79766175 --target /tmp/restore-work
enter password for repository:
restoring <Snapshot of [/home/user/work] at 2015-05-08 21:40:19.884408621 +0200 CEST> to /tmp/restore-work

Use the word latest to restore the last backup. You can also combine latest with the --host and --path filters to choose the last backup for a specific host, path or both.

$ restic -r /srv/restic-repo restore latest --target /tmp/restore-art --path "/home/art" --host luigi
enter password for repository:
restoring <Snapshot of [/home/art] at 2015-05-08 21:45:17.884408621 +0200 CEST> to /tmp/restore-art

Use --exclude and --include to restrict the restore to a subset of files in the snapshot. For example, to restore a single file:

$ restic -r /srv/restic-repo restore 79766175 --target /tmp/restore-work --include /work/foo
enter password for repository:
restoring <Snapshot of [/home/user/work] at 2015-05-08 21:40:19.884408621 +0200 CEST> to /tmp/restore-work

This will restore the file foo to /tmp/restore-work/work/foo.

You can use the command restic ls latest or restic find foo to find the path to the file within the snapshot. This pass you can then pass to –include in verbatim to only restore the single file or directory.

Restore using mount

Browsing your backup as a regular file system is also very easy. First, create a mount point such as /mnt/restic and then use the following command to serve the repository with FUSE:

$ mkdir /mnt/restic
$ restic -r /srv/restic-repo mount /mnt/restic
enter password for repository:
Now serving /srv/restic-repo at /mnt/restic
Don't forget to umount after quitting!

Mounting repositories via FUSE is not possible on OpenBSD, Solaris/illumos and Windows.

Restic supports storage and preservation of hard links. However, since hard links exist in the scope of a filesystem by definition, restoring hard links from a fuse mount should be done by a program that preserves hard links. A program that does so is rsync, used with the option –hard-links.

Printing files to stdout

Sometimes it’s helpful to print files to stdout so that other programs can read the data directly. This can be achieved by using the dump command, like this:

$ restic -r /srv/restic-repo dump latest production.sql | mysql
