Exchange GRT question

This issue has been solved. See solution.
Hi
We have a heavy exchange mailbox server (1TB) and I find out that I can use GRT only on full backups. I cannot take a full backup every day and since mailbox server are clustered I cannot use CPS either. Is there any way to provide mail-level restore to users on each day of week without taking daily full backups?

Whoa...1TB of Exchange
Whoa...1TB of Exchange data...! Is that in the same storage group, or multiple?
Your only other option is to look into Incremental/Differential backups, or alternatively consider BE 2010 with deduplication. This would backup your IS fully the first time, and only changes thereafter. Furthermore, multiple emails that are the same would only be backed up once.
For GRT to work properly, it has to be a Full backup...there is no way to get around that. You could look at speeding it up by sending the backup to disk first, before streaming off to tape. The fastest way here would then be a SAN.
If you find this is a solution, please mark it as such.
thanks for answer
Yeah that is a huge server for a customer with around 1200 very active users! It has been distributed across several storage groups.
I've had a bad experience with deduplication with our own exchange 2010 server. Deduplication service and database will fail eventually and I had very little success rate for exchange backup jobs will destination is deduplicated. Do you have good experience?
In real world, how much do you think would be other backups rather than first full?
You can run the full backup
You can run the full backup and then the subsequent incremental bckups. You can get the GRT in the incremental as well but below are the condidtions:
1> Both the full and incremental should be in the policy
2> Both of them should be going to same volume on the disk.
So if you can configure your backups going to SAN disk then definately you can run the grt backup for the incremental as well.
The exchange incremental doesn't work on tape, so when you create a policy and incremental is going to tape then you will not be able to see the individual itemss but if you duplicate the tape data to disk then you should be able to see the individual items.
I've only started playing
I've only started playing around with deduplication now, and it works. Not quite what I thought, but then again, I haven't configured it much, and haven't tried it with Exchange.
Have you not considered archiving mails out?
If you find this is a solution, please mark it as such.
thanks sazz
your answer was great. I tested it and it worked perfectly with exchange 2007. But surprisingly it wont work with our own exchange 2010. The incremental backup will only backup logs. Does anybody have any idea?
