NAME
backintime - a simple backup tool for Linux. This is command line tool. The graphical tools are: backintime-gnome and backintime-kde4. 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. OPTIONS
-b, --backup take a snapshot now (if needed) --backup-job take a snapshot (if needed) depending on schedule rules (used for cron jobs) --snapshots-path display path where is saves the snapshots (if configured) --snapshots-list display the list of snapshot IDs (if any) --snapshots-list-path display the paths to snapshots (if any) --last-snapshot display last snapshot ID (if any) --last-snapshot-path display the path to the last snapshot (if any) -h, --help display a short help -v, --version show version --license show license SEE ALSO

NAME
fssnap - create temporary snapshots of a file system SYNOPSIS
fssnap [-F FSType] [-V] -o special_options /mount/point fssnap -d [-F FSType] [-V] /mount/point | dev fssnap -i [-F FSType] [-V] [-o special_options] [/mount/point | dev] DESCRIPTION
The fssnap command creates a stable, read-only snapshot of a file system when given either an active mount point or a special device con- taining a mounted file system, as in the first form of the synopsis. A snapshot is a temporary image of a file system intended for backup operations. While the snapshot file system is stable and consistent, an application updating files when the snapshot is created might leave these files in an internally inconsistent, truncated, or otherwise unusable state. In such a case, the snapshot will contain these partially written or corrupted files. It is a good idea to ensure active applications are suspended or checkpointed and their associated files are also consis- tent during snapshot creation. File access times are not updated while the snapshot is being created. A path to the virtual device that contains this snapshot is printed to standard output when a snapshot is created. OPTIONS
The following options are supported: -d Deletes the snapshot associated with the given file system. -F FSType Specifies the file system type to be used. The FSType should either be specified here or be determined by matching the block special device with an entry in the /etc/vfstab table, or by consulting /etc/default/fs. -i Displays the state of any given FSType snapshot. If a mount-point or device is not given, a list of all snapshots on the system is displayed. When a mount-point or device is specified, detailed information is provided for the specified file system snapshot by default. The format and meaning of this information is file-system dependent. See the FSType-specific fssnap man page for details. -o special_options See the FSType-specific man page for fssnap. -V Echoes the complete command line, but does not execute the command. OPERANDS
The following operands are supported: /mount/point The directory where the file system resides. EXAMPLES
See FSType-specific man pages for examples. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
/etc/vfstab Specifies file system type. /etc/default/fs Specifies the default local file system type. ATTRIBUTES
