I have a drive with data on it. I dont want to use RAID, instead I want to do hourly backups to a second drive. I basically want to mirror the data drive and resync every hour.
It is inefficient to re-move the data each time so really I only want to move across what changes. I.e if I add a new file to the data drive only that file will be moved across.
What tools are there for doing this on the command line? I used to use luckybackup on Ubuntu but now im on commandline debian.
