Hello, I have setup MRM policies in our organization. The policy is to move anything older than 3 years to deleted items and it will get permanently deleted from deleted items after 14 days. I see it is generating extra logs because of moving and deleting activity. My log disks have been filling up. Is there a way to calculate the amount of logs exchange will generate? I need to expand my logs disk accordingly. I have about 600 mailboxes that needs MRM. Any help is appreciated!

Not really, it will depends on how many items meet the criteria in each users mailbox. I would take a rough estimate and if need be increase in chunks of 10GB.Sukh

okay, if i were to figure out the amount, is it as simple as: if a folder in a user's mailbox contains 300MB that have been identified by MRM to delete, will it create 300MB worth of log files?

I dont think its as simple as that, what I would do is create a test db, create a mailbox , generate 300mb , delete and keep an eye onthe logs. Seperate the logs from prod.Sukh

A delete operation doesn't record the data being removed, just the fact that the data's been removed. It's a pretty small amount of data. I think the increase in log files is recording the movement of the data from one folder to another (i.e. the Deleted Items folder). During the initial deployment of MRM the log file generation can be substantial if you're moving data around (which is what you're doing). It's a good idea to deploy MRM gradually to a small subset of mailboxes at a time. If your bacup schedule removes unnecessary log files every day, then enroll a small subset of users each day. The 1st set of mailboxes will create a big bunch of log files on the 2nd day, the 2nd batch of mailboxes will create a big bunch of log files on the 3rd day, etc. After you've enrolled all the mailboxes the only activity will be the items in each mailbox that exceed the 3-yer expiry date. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

No, I think it will not create 300MB worth of log files. The log files will record information for the items, not the item.

So if a folder in a user's mailbox contains 300MB that have been identified by MRM to move, will it create 300MB worth of log files?

It will certainly generate log data. Whether it amounts to 300MB I don't know. Information in the database is compressed, and it's not decompressed when it's moved. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

wont create 300MB worth of data.Sukh
