help rsnapshot FAQ

How does rsnapshot save disk space when each snapshot looks complete?

rsnapshot uses rsync to create snapshots and hard links for files that have not changed. The unchanged files appear in every snapshot but share the same stored data, so new space is mainly used by changed or new files. [rsnapshot FAQ](https://rsnapshot.org/faq.html)

What do hourly, daily, weekly, and monthly mean in rsnapshot?

They are rotation levels defined in the configuration, not automatic time periods built into the program. You normally run rsnapshot hourly first, then higher levels such as daily and weekly rotate the existing snapshots. [rsnapshot FAQ](https://rsnapshot.org/faq.html)

Does rsnapshot schedule backups by itself?

No. rsnapshot performs the backup and rotation commands, but a scheduler such as cron usually runs those commands on Linux or macOS. The exact schedule depends on the cron entries and intervals you configure. [rsnapshot FAQ](https://rsnapshot.org/faq.html)

Can rsnapshot back up files from another computer?

Yes. It uses rsync and can copy from remote systems, commonly over SSH, while retaining snapshot history at the destination. The destination filesystem must support hard links for rsnapshot's space-saving method to work. [rsnapshot FAQ](https://rsnapshot.org/faq.html)
