Question Best way to compare 2 directory heirarchies?


Hello all. I'm about 2 weeks overdue for a backup of my FTP server, so I figured I should do it now, lest my RAID-0 array fail and take a large ammount of data with it.

Due to some recent instability caused by the CPU overheating, I don't completely trust the integrity of the data currently on the server, so instead of taking the risk of overwriting good data with bad data, I want to make an incremental backup, just copying the new files and directory structure changes (files moved, directories renamed, etc) made since the last backup.

The problem lies in getting a list of differences between the server copy (/pub) and backup copy (/mnt/hd/pub). I tried dumping ls -lR to files and running diff against them, but it produces a useless dump of EVERY difference, even just entries that get shifted down a line or so due to new entries.

Is there any good way to do this? Thanks for any advice!

Well, if you know the date of your last full backup, you could use "find" to
find all the files, etc. that are newer than said date.

man find
