Greetings All,
I am looking for the best way to do online/offsite, automated,
nightly,
incremental file backup for my mail server.
these days i would go ahead and move the mailserver on a
VMware-vCenter and
with the essentials-plus license you get VMware-DataRecovery which
makes
real good deduplication from some terabyte down to 250-500 GB and is
snapshot-based
rsync of a running filesystem-based mailserver will mostly not be
consistent
and shut down the services for backups is bad
http://www.vmware.com/products/data-recovery/overview.html
you can restore the whole machine as a running clone and give it
a free ip-address (test recovery)
________________________________
on the other hand we are using dbmail and with mysql/innodb as backend
a replication salve is easy to set up which you can always put down
automated and use rsync for a offiste-backup of the slave
we are using both, daily offsite-backup and weekly VDR 3 weeks back
and additionally a weekly rotate on the slave wher a simple
"service mysqld stop; service mysql-lastweek start" will switch
the imap-server a week back to restore mails with imapsync
________________________________
depends on your needs, but this are ours solutions after a long
time thinking how we can get as much backups as possible with
minimzed overhead in work and storage and zero downtime
The way my service works is they already put me in a VMware jail and
I don't have visibility outside it. (Although I am on a dedicated
machine, their VMware jail allows them to enforce things like their
security policy, disk quota, exact Linux kernel, I get no custom
modules, etc.)
I infer, without any hard knowledge, that SimFS is a journalling
system, and that the VMware can do nice tricks like snapshotting in
the background of a single consistent point in time, while the
virtual Linux system continues to operate and make changes. I am
getting the strong feeling that if I want to get my ideal, I will
have to switch to a service that does give me full VMware control and
thus the snapshotting control. Currently my provider does a
one-size-fits-all, weekly snapshot for the most recent 4 weeks, and
making a restore request goes to their sysadmin ticketing system and
takes days and days. :-(
I doubt this has anything to do with VMWare. SimFS and unable to load
Kernel Modules looks more like Linux container like OpenVZ/Virtuozzo.
With this you only have userland for your backup.

Andreas
Yes, you must be right because there are vzquota and vzquotafix scripts
in /etc/rc.d/init.d.
