Hi Sharon,
thanks for that, that confirms my guess. Now I'll just have to get IT to work
out the appropriate scripting to sync up a remote stop/restart of the service
with the clone operation.
Thanks,

Subject: Re: [Artifactory-users] Backup mechanism(s)
Hi Hugh,
One of the easiest ways to backup Artifactory is to use the built-in backup
feature. It allows you to backup everything (including binaries, metadata, and
configuration) and it's done in the background without the need to shut down. A
clone or a snapshot of an incremental backup directory or of a completed full
backup is safe to use.
The other popular method is to backup Artifactory home folder and binaries for
example with rsync and the database with the database specific tool, for
example mysqldump for MySQL.
Creating a clone/snapshot of Artifactory and the database while they are
running might create minor discrepancies between the binaries and the files
metadata. This can happen if there is write load (transaction) on the server.
Corruption of the database is quite rare (especially with databases that
maintain a redo log) but we cannot guarantee it will not happen.
Hope this helps.
Sharon

Hi all,
I have a few questions about backing up Artifactory.
My main question is, what is/are the recommended or supported mechanism/s, on
Windows Server? I see
http://www.jfrog.com/confluence/display/RTF2X/Managing+Backups (we're still on
2.6.4) describes the internal backup mechanism, which is what we're using, by
default. However, our system is hosted on a VM, and our IT guys use a
combination of "Symantec Backup Exec 2010" and "Veeam Backup and Replication"
to do a nightly clone of the VM to a separate SAN in a physically separate
location. I'm assuming that, if that VM clone ran while Artifactory was doing
its own internal backup, I might end up with inconsistencies between metadata
and filesystem, or possibly even outright corruption of either/both. I
suggested doing a scheduled shut-down of the service, running the backup, and
restarting the service, but there are a couple of problems with that.
* First, the systems we have don't let us guarantee that the backup
won't run until the service has successfully shut down (and similar problems on
service restart).
* Second, we expect to soon have other sites in two different time
zones, with remote repos pointing to our locals, so we don't want to shut down
during our night, when they're at work!
A related question is, does the internal backup mechanism back up absolutely
everything you need to re-build your Artifactory system? I'm assuming it backs
up all files and metadata but, e.g., does it back up the config descriptor and
security descriptor? What about the Jetty config? Anything else I'd need?
Lastly, is there a good way to test the backups, beyond "fetch the most
recently published artifacts and check the hashes"?
Thanks for any advice you can give,
