using another backup format. So I might use backuppc for my main backup
system, but once a month do a full backup using dump onto a completely
I have been sucessfully using 8GB dual layer DVDs for some of my
backups/archiving and now that the price of Blu ray has come down I am
about to experiment with that. I have been writing dump format files to
the DVD's and then writing an SHA256 checksum for each dump file so it's
very easy to verify the integrity of the dump.
I am also about to try daily emcrypted backups to http://rsync.net along
with periodic archival to blu-ray disk for one of my backup needs.
I have noticed that two of the recently mentioned backup packages,
duplicity and storebackup appear to support some kind of block level
deduplication where you can backup a large file, database or possibly
even a disk partition, incrementally over the network. I am interested
in trying that for backup up of mysql databases.
