It’s always a good idea to keep backups of all of your data in multiple places. Every Linux or Unix sysadmin must master the art of backups if you want to keep your data forever. Most sysadmin recommend and follows the 3-2-1 rule:
At least three copies of data.
In two different formats.
With one of those copies off-site.
Tarsnap is one of such off-site backup sites. It’s a secure online backup system for UNIX-like system. This service encrypts and stores data in Amazon S3.
