SYNOPSIS

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

DESCRIPTION

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.

user-callback
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 progile id (1=Main Profile, ...).

The second argument is the progile name.

The third argument is the reason:

1

Backup process begins.

2

Backup process ends.

3

A new snapshot was taken. The extra arguments are snapshot ID and snapshot path.

4

There was an error. The second argument is the error code.

Error codes:

1

The application is not configured.

2

A "take snapshot" process is already running.

3

Can’t find snapshots folder (is it on a removable drive ?).

4

A snapshot for "now" already exist.
