Should I Use rsnapshot?

rsnapshot.org·Analyzed 1 week ago··Based on 12 sources

rsync-based backup utility

Verdict

Depends

Buy it if you administer Linux boxes and are comfortable editing a text config file and cron.

Confidence: Medium

Skip it if you want a GUI, built-in encryption, or someone to call when backups break.

Free, rock-solid rsync snapshots for Linux admins. Wrong pick if you want a GUI, encryption, or vendor support.
