Rsync backup to Synology Diskstation

2025-03-25

This could change but it works for me.

My Diskstation isn't always on, so I run this from the command line rather than cron.

To avoid errors devices and links are skipped, permissions, times, group and owner are not written and files are compared by size only.

Ssh is configured with ssh-copy-id for passwordless access and host:port details in .ssh/config

Note: I set the rsync options on the diskstation but had to chmod 755 my +diskstation's home folder before passwordless ssh worked
