I use a script[*] to monitor if backups are being taken regularly. It also checks the current storage consumed. While I'm not actually using those numbers for anything, my reasoning when I wrote the script was that I could track the growth of data over time and have my monitoring complain if the first derivative crossed some threshold either way.
Not very exciting. After moving some stuff around so my monitoring doesn't connect as root so much, the --print-stats bit stopped working because it can't read the cache directory. Fair enough. I could presumably set an ACL on the cache directory but I wonder if this sort of thing really needs access to the cache. I know that the Tarsnap server doesn't know anything about the individual archives, but it surely knows about the total amount of data stored. Colin: how do you feel about a variant of --print-stats that can print out the storage (and maybe the bandwidth too?) use for a particular key? I mostly care that my backups work but ... monitor all the things. :) Philip [*] https://trouble.is/~philip/check_tarsnap.sh.txt -- Philip Paeps Senior Reality Engineer Ministry of Information
