'''Back In Time''' is a backup application for [[Linux|GNU/Linux]] with a graphical interface written in [[Qt_(software)|Qt]] and a command line interface. It is available directly from the [[Software repository|repositories]] of many [[GNU/Linux distributions]]. Released under the terms of the [[GNU General Public License]] (GPL), it is [[free software]].

Back In Time uses [[rsync]] as backend and has the characteristic feature of using [[hard link]]s for files which are identical in snapshotsbackups at different times, thus using disk space just once for files that remained unchanged. It is possible to use several backup profiles, e.g. for backups on different hard disks and also to create schedules. [[Symbolic link]]s can be backed up, both absolute and relative ones, but hard links cannot be treated as such due to the used backup method. Back In Time also supports encryption of backups and backup over [[SSH]].

Advantages of the hard link method are that it is easy to look at snapshots of the system at different times and also easy to remove old snapshots compared to incremental backup methods which save difference information between consecutive backup times. However, a drawback of Back In Time is that it does not allow for compression, and requires file systems that support hard links on the backup ___location.
