backing up my repositories, anything special needed?

[Gábor Farkas]

hi,

i create daily backups of my important files (well, not yet, but working
on it :), which include also my mercurial repositories...

is it enough to simply backup the directory which contains the repositories?

for example, what happens if someone is pushing to a repository at the
same time when it's backed up?

will that be ok?

or should i rather do something like:

- create a temp directory
- clone all my repositories into that directory
- backup that temp directory

?

or is hg-bundle or hg-export or something of that kind better suited for
this?

p.s: if i have the repositories on a filesystem that can create atomic
snapshots(like zfs), then is it safe to simply create a snapshot of the
repository-directory, and then back it up?

thanks,
gabor
