[BUGS] Remote backups, imap too

[Jerahmy Pocott]

Hello,

Just looking for some options/suggestions on remote backup tools,
I was thinking of using rsync, but then I was thinking maybe it's not
really good for backups?

I mean incremental backups of large amounts of data over wan, I
like how rsync only sends the changes rather than the entire file,
but then if the source file has been removed I may not want the remote
file to also be removed..

The other issue is the method of connection to remote storage, I
have some of these 'lacie ethernet disk mini' things, they support
smb, afp, ftp, bonjour. I had considered using samba to mount them
and then rsync, but I'm not entirely sure how a samba mount behaves
with rsync, has anyone tired it? The file permissions might be an
issue?

(disk specs http://www.lacie.com/au/products/product.htm?pid=10844)

You can also download the source for these drives os, it looks
to be based on a linux kernel. I suppose it might be possible to
build a version with rsync in it..

And totally unrelated to this, anyone care to recommend an imap
mail server for bsd? I'v only ever used sendmail..

Cheers,
J.
