-Due to the [[public:2017-06-14_data_extinction_event_investigation_report|fiasco]] of running ''rm -rf'' on my home partition, and wiping out all my backup snapshots, I realised that it is important to have some sort of offline backups. Snapper [([[http://snapper.io/|Snapper, The ultimate Snapshot Tool for Linux]])] creates snapshots, but manual operations are required to move those snapshots off to external backup devices (in order to offline backups). A better solution is desperately needed. I discovered Btrbk [([[https://github.com/digint/btrbk|GitHub - digint/btrbk: Tool for creating snapshots and remote backups]])]. +Due to the [[public:2017-06-14_data_extinction_event_investigation_report|fiasco]] of running ''rm -rf'' on my home partition, and wiping out all my backup snapshots, I realised that it is important to have some sort of offline backups.

-The extra ''[[ssh://127.0.0.1/mnt/home]]'' paragraph basically follows the "Example: multiple btrbk instances" on the [[https://github.com/digint/btrbk|btrbk's Github page]]. This allows ''snapshot_dir'' to get cleared up locally. If you write everything in one paragraph, then btrbk refuses to clean up snapshots, because external hard drives are not connected. If you write another paragraph of ''volume /mnt/home'', then btrbk complains that the two snapshots are created at the same directory. +The extra ''[[ssh://127.0.0.1/mnt/home]]'' paragraph basically follows the "Example: multiple btrbk instances" on the btrbk's Github page[(btrbk_github)].
