Cronopete is a backup utility for Linux, modeled after Apple’s
Time Machine. It aims to simplify the creation of periodic backups.
By default, cronopete does a backup each hour, adding to the
new backup only the files that have changed since the last one.
This allows to return to a previous backup in an specific
instant of time. It is important to have a generous external
disk for backups. It is strongly recommended to use a disk of,
at least, twice the size of the data to store. SSD disks aren’t
recommended, because their speed gain is unnecessary for a backup,
and are much more expensive than a mechanical disk. An external,
USB3, mechanical disk with plenty of free space is an excellent
choice for storing your backups.
