I have a few questions about the backup and restoration process.
Firstly is backups accessed through the web interface. If we were to be left with nothing but them (the full and incremental backups) would we be able to restore our system with just those? Or do we need to have a full backup of the /opt/zimbra directory?
I see folders in the backups for accounts, ldap, redologs, session.xml and sys.
If you are able to do a restore with those backups, is it done through the web interface for non-account related things, or would that be done through the command line? Also how easy is this?
Lastly, how do the full and incremental backups work? Because they seem to be fairly inconsistent in size -- mainly talking about the full backups. Does it work more around the lines that a full backup is everything since the last full? Why is there such a disparity in sizes between the full backups (see below)? Once one of the full backups hits the deletion time does the next full backup pickup the data that that full was covering (is this why there's one full at 180G and the next closest is 16G?)?
I'm sorry for so many questions, I know it's a little unorganized, but any help is greatly appreciated!Code:zimbra@server:~/backup/sessions$ du -h --max-depth=1 . 158M ./incr-20080930.050005.611 207M ./incr-20081001.050008.233 180G ./full-20081004.050004.143 258M ./incr-20081008.050006.463 8.1G ./full-20081011.050007.136 420M ./incr-20081015.050004.579 16G ./full-20081018.050004.026 365M ./incr-20081002.050004.956 373M ./incr-20081003.050005.608 278M ./incr-20081005.050011.455 122M ./incr-20081006.050006.597 284M ./incr-20081007.050010.403 498M ./incr-20081009.050008.952 400M ./incr-20081010.050006.284 576M ./incr-20081012.050006.029 138M ./incr-20081013.050008.654 299M ./incr-20081014.050005.140 5.2G ./incr-20081016.050006.582 446M ./incr-20081017.050004.978 468M ./incr-20081019.050010.869 92M ./incr-20081020.050005.046 536M ./incr-20081021.050012.687 337M ./incr-20081022.050009.621 275M ./incr-20081023.050016.021 356M ./incr-20081024.050010.692 9.8G ./full-20081025.050007.107 1.4G ./incr-20081026.050006.144 128M ./incr-20081027.050005.500 412M ./incr-20081028.050005.634 282M ./incr-20080928.050010.209 120M ./incr-20080929.050006.062 6.2G ./full-20081009.124053.116 233G .
