Mailbox level backup on 2007 Passive node in CCR

[theravager]

Anyone know if it is possible to do mailbox level backups on the passive node of a 2007 ccr cluster?

The CV books online documentation is very weak in this area it kinda aludes that it may but dosent actually say it.

Cheers

Exchange 2007 backup is a million miles away from 2003 due to the lack of MAPI support but, yes you can do mailbox level

You can use either a off or on host proxy configuration to do a mailbox level backup ...if you use onhost proxy then you need to either install Outlook or MAPI drivers on the mbx role host (as well as some other configs)...then you point the subclient to the proxy host

Well it’s not as easy as all that.
The Exchange MB, PF and WF agents are all 32bit agents.
There are no 64bit agents for these MAPI reliant agents as the MAPI interface is 32bit only. Microsoft decided that brick-level wasn’t the way forward.

So, you could go the Microsoft way and recover via the recovery storage group.

Those 32bit agents will install on the Exchange 2007 server providing you create the regkey that permits multiple instances and allows a 32bot install on a 64bit system.
But you will need to either install Outlook or the admin tools in order to lay down the MAPI interface. This can get a bit messy, especially on a cluster.

So, best way is to use a proxy method instead.
Don’t forget though, you’ll only get about 15-30GB/h transfer rate so if there is lots of GB you may want to not even bother going down this road, use RSG instead!

The reason i asked is if mailbox level backups work on the passive node the speed of backup doesn't really matter as it can be done in business hours anyway.

Using RSG isn't very efficent when you can restore a item in a mailbox in minutes as opposed to amount of work a staff member needs to do to use RSG + restoration time of a database.

If mailbox level backups on the passive side don't work then yes that definately will involve a rethink on what sort of SLAs we can put on mail restores.

If brick-level backup is what you want that thats what you shall have. Yes you can install the MB agent on the passive node of an Exchange 2007 cluster.

While its possible to backup your Exchange DB from the passive it would be a bit harder to do this with Mailbox backups as even with a mail proxy you are pointing this to the Virtual Mailbox node which would then access the data from the active node, this is due to the fact that the mail proxy is simualating being a MAPI client that has to access the data the same way as outlook clients.

Also what i recommend to customers is to install the Mail proxy on the Media agent rather then the exchange node this allows you do not have a 32 bit client on the EX server and also means if node 1 (where the agent would have been installed)goes down when node 2 comes up you are still pointing to the virtual node and no config changes are nessary

hope this helps
