Back In Time is a simple backup tool for Linux. This is the Qt5 version. For more information about Back In Time see backintime man page.

If you want to run it as root you need to use 'backintime-qt_polkit'.



Force to use checksum for checking if files have been changed. This is the same as 'Use checksum to detect changes' in Options. But you can use this to periodically run checksums from cronjobs. Only valid with backup, backup-job and restore.

--config PATH

Read config from PATH. Default = ~/.config/backintime/config


Show debug messages.


Restore and delete newer files which are not in the snapshot. WARNING: deleting files in filesystem root could break your whole system!!! Only valid with restore.

-h, ā€‰--help

Display a short help


Don't unmount on exit. Only valid with snapshots-path, snapshots-list-path and last-snapshot-path.


Show license


Create backup files before changing local files. Only valid with restore.


Do not install crontab entries. Only valid with check-config.


Temporary disable creation of backup files before changing local files. Only valid with restore.


Only restore files which does not exist or are newer than those in destination. Using "rsync --update" option. Only valid with restore.

backup | -b | --backup

Take a snapshot now.

backup-job | --backup-job

benchmark-cipher | --benchmark-cipher [FILE-SIZE]

Show a benchmark of all ciphers for ssh transfer.


Verify the profile in config, create snapshot path and crontab entries.

decode | --decode [PATH]

Decode encrypted PATH. If no PATH is given Back In Time will read paths from standard input.

last-snapshot | --last-snapshot

Display last snapshot ID (if any)

last-snapshot-path | --last-snapshot-path

Display the path to the last snapshot (if any)

pw-cache | --pw-cache [start|stop|restart|reload|status]

Control the Password Cache Daemon. If no argument is given the Password Cache will start in foreground.

remove[-and-do-not-ask-again] | --remove[-and-do-not-ask-again] [SNAPSHOT_ID]

Remove the snapshot. If SNAPSHOT_ID is missing it will be prompted. SNAPSHOT_ID can be an index (starting with 0 for the last snapshot) or the exact SnapshotID (19 characters like '20130606-230501-984'). remove-and-do-not-ask-again will remove the snapshot immediately. Be careful with this!

restore | --restore [WHAT [WHERE [SNAPSHOT_ID]]]

Restore file WHAT to path WHERE from snapshot SNAPSHOT_ID. If arguments are missing they will be prompted. To restore to the original path WHERE can be an empty string '' or just press Enter at the prompt. SNAPSHOT_ID can be an index (starting with 0 for the last snapshot) or the exact SnapshotID (19 characters like '20130606-230501-984')


Shutdown the computer after the snapshot is done.


Remove snapshots based on the configured Smart-Remove pattern.
