We're backing up w/ Legato (under linux w/ a network based server
running on Solaris) and it works fairely well.. 1 of our servers has
1Million files and 6Gb of data in the store. The other as just under
1Million using 10 Gb. For each a full backup of the store takes about 1
hour.

Sure. As of 2.4.1 (from their NEWS file):

That's what I do with vxfs on UnixWare.

On a smaller scale, we use amanda to do nightly backups of the mail
spool, and we have successfully recovered after mails have been deleted.
With one of our clients, we use standard NetBackup to do nightly
backups, which works just as well.
As for up to the minute backups though, don't know a g

Other than filesystem snapshots (if your underlying volume manager knows
about it) i don't see some very us
I use TSM to backup my Cyrus mail store. Over 7 million files so it does
take TSM almost 8 hours to go through the store on a nightly basis.

I've seen some interesting comments in this thread so far, but none
seem to discuss our concerns: We have a fairly large installation,
and due to the file-per-message nature this makes for millions of
small files which can wreak havoc on a backup system. We're using
VXFS on Solaris, but are using
I'm new to cyrus, just testing it for 2 weeks and getting very good
reviews from our users. I think cyrus it is a very powerful piece of
software, in addition it does a wonderful job with a very small
footprint, on the other hand, a good backup solution is our chief
concern, our current backup
It would be nice to add a backup section to the documentation.
Live backup is supported with Cyrus, though running "dump" on a live
filesystem is only to be done with care. We use vxfs on Solaris and
snapshots and have been happy with it.
The databases are backed up by Cyrus 2.1 every checkpoin
there's not too many of them :-)

As another newbie, I was sure hoping someone would share their

I would add to Boris' question what the best way would be to create poor

Dear all,
I would like to know the best way of backup/restore cyrus system. What are the
steps required?
Are there "online backup" methods available? What are the files required to backup
and how can
I restore it on the same machine/ another machine?
Many thanks!
