backintime - a simple backup tool for Linux.

This is command line tool. The graphical tools are: backintime-gnome and backintime-kde4.


backintime [ --backup | --backup-job | --snapshots-path | --snapshots-list | --snapshots-list-path | --last-snapshot | --last-snapshot-path | --help | --version | --license ]


Back In Time is a simple backup tool for Linux. The backup is done by taking snapshots of a specified set of folders.

All you have to do is configure: where to save snapshots, what folders to backup. You can also specify a backup schedule: disabled, every 5 minutes, every 10 minutes, every hour, every day, every week, every month. To configure it use one of the graphical interfaces available (backintime-gnome or backintime-kde4).

It acts as a 'user mode' backup tool. This means that you can backup/restore only folders you have write access to (actually you can backup read-only folders, but you can't restore them).

If you want to run it as root you need to use 'su'.

A new snapshot is created only if something changed since the last snapshot (if any).

A snapshot contains all the files from the selected folders (except for exclude patterns). In order to reduce disk space it use hard-links (if possible) between snapshots for unchanged files. This way a file of 10Mb, unchanged for 10 snapshots, will use only 10Mb on the disk.

When you restore a file 'A', if it already exists on the file system it will be renamed to 'A.backup.currentdate'.

For automatic backup it use 'cron' so there is no need for a daemon, but 'cron' must be running.


During backup process the application can call a user callback at different steps. This callback is "$XDG_CONFIG_HOME/backintime/user.callback" (by default $XDG_CONFIG_HOME is ~/.config). The first argument is the reason:
Backup process begins.
Backup process ends.
A new snapshot was taken. The extra arguments are snapshot ID and snapshot path.
There was an error. The second argument is the error code.
Error codes:
The application is not configured.
A "take snapshot" process is already running.
Can't find snapshots folder (is it on a removable drive ?).
A snapshot for "now" already exist.
