Now, I want to backup the data (hourly) on the Synology NAS to the LaCie NAS. Synology offers two options:
- Built-in backup to an rsync server. This isn’t a real backup; it's just a mirror. If you accidentally delete a file, it’s also deleted from the ‘backup.’
- Synology Time Backup. This does support multiple versions. However, you can only use it to backup to another Synology NAS, not to an rsync server.
Using the SSH access on the Synology NAS, I could also install free software tools, such as rsnapshot, BackupPC, rdiff-backup or Bacula. However, all these tools either:
- Cannot backup to a remote system.
- Require a daemon to be running on the remote system.
- Warn against backing up to a network drive mount, due to limitations regarding hardlinks.
My last resort would be to gain root access to the LaCie NAS. That would allow me to install Debian, and therefore any software I want. But I’d prefer not to go that route, as I would no longer be able to easily update the firmware.
Are there any tools that I could use to achieve hourly backups? Or have I reached the wrong conclusion regarding the tools mentioned above?
EDIT: I’ve given up. Using root access and configuring rsnapshot was by far the easiest way. I created a manual on GitHub.
