<p><b>New page</b></p><div>Various tools for full or partial backup are described in the Software -> Backup section of this wiki. Suggested techniques include:<br />
<br />
== Data ==<br />
*rsnapshot or dirvish<br />
**provides freqent, space-efficient, reverse-delta incremental backups<br />
*snapshot<br />
**generally requires that data be on a BTRFS filesystem and uses inbuilt snapshotting function within that filesystem<br />
**can require huge storage space<br />
*rsync<br />
**simple implementations synchronise files in a backup repository with those in a working system<br />
***does not provide incremental, historic view<br />
***rsnapshot/dirvish are a simpler way to provide incremental backups<br />
<br />
== Operating System ==<br />
<br />
=== Minimal Approach ===<br />
a backup of the folder /etc can assist restoring settings to a '''fresh''' installation of the same distribution and release.<br />
<br />
=== Reverse Delta ===<br />
rsnapshot or dirvish can be configured to do frequent backups of system as well as data files<br />
*frequency could vary between data & system files<br />
<br />
=== Snapshot ===<br />
this function within BTRFS can produce system and/or data snapshots, at various trigger points<br />
<br />
=== Cloning ===<br />
This is an "off-line" technique:<br />
*does not lend itself to repetitive, incremental backups<br />
*might be the best approach for replacing HDD/SSD containing system files<br />
