Hi,
I suppose this is a strange request. I used to use rsync to create and
update a mirror of my /home directory (on /backup/home, where /backup is an
external USB drive). This is my home PC, used just by my family, so
updating the mirror only takes a few minutes, and I've had cron running it
every hour. I've just switched over to rdiff-backup, which is working like
a charm. However...I like the idea of having the mirror as up-to-date as
possible, but really don't need the hourly incremental history. Is there
any way to update the mirror (in /backup/home) on an hourly basis, but only
create incremental backups daily?
I have come up with a way to do it, but it's a bit ... hacky.
rdiff-backup /home to /backup/home.rdiff, daily
rsync --link-dest=/backup/home.rdiff /home /backup/home.rsync, hourly
If I'm right about how things work, that'll give me a rdiff-backup mirror in
/backup/home.rdiff with daily incremental backup history, and a mirror in
/backup/home.rsync that's updated hourly, and any files that are identical
between the daily and hourly mirrors will be hard-linked so as not to waste
space.
Does that sound right, and is there an easier way? It would be nice to be
able to run rdiff-backup hourly, with a parameter telling it to only
generate incremental history daily.
Thanks, and thanks for a great tool!
Randy
