I suggest that instead of using rsync directly you use rsnapshot. You can set it up so that it only copies if DRIVE2 is there. The cron entries let it happen automatically. What I do is different from what you are doing. I have an SSD where all my live stuff exists. I have four 4TB drives sat ups as a RAID. I use amanda for backups from the SSD to the RAID, analogous, I take it, to your DRIVE1. I have three USB 4TB drives which I rotate between my offsite location and take with me on trips, analogous to your DRIVE2. I use rsnapshot to back part of the RAID up to the USB drives in rotation. My offsite drives do vary in free space, but diffing between the RAID and the offsites indicates that the data is intact. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
