I had a heckuva time getting hard link snapshot backups to work. I traced my troubles down to what appears to be an rsync bug:
This works as expected (a hard link is made) ************ rm -rf a b mkdir a b echo foo > a/tmp rsync -a a/ b/a.1 rsync -a --link-dest=../a.1 a/ b/a ls -i b/*/tmp the above yields, for example: 4235593 b/a.1/tmp 4235593 b/a/tmp ************ This does not (a copy is made instead of a hard link) ************ rm -rf a b mkdir a b echo foo > a/tmp rsync -a a/ b/a.1 rsync -a --link-dest=a.1 a b ls -i b/*/tmp the above yields, for example: 4235593 b/a.1/tmp 4235595 b/a/tmp ************ The only difference is running the second rsync without a "/" following the source (adjusting other arguments accordingly). But my understanding is that these are two ways of running rsync that should accomplish precisely the same thing. That is: rsync a/ b/a is supposed to do exactly the same thing as rsync a b I happen to prefer the latter syntax, and that's apparently how I got into trouble. Am I missing something here? Should I file a bug report? I tried this on several setups and got the same result, but for reference here's one: rsync v 3.0.6 on (stock) Ubuntu 9.10 -- Please use reply-all for most replies to avoid omitting the mailing list.
