As with each migration of exchange comes the problem of restoring the previous systems' from backup. Once your users will have been migrated to 2010, how to recover mails from 1 month, one year ago or more ?
The Official guidance for this is to keep one server with a previous version of exchange. However, I've seen that there are tools (the one i saw was from Ontrack) that allow the restore to a simple file server then mount and extract the data from there.
Are there people here using those tools and if so with which backup solutions ? (we use Netbackup 6.5). Is the backup process the same or are there caveats to the use of those tools ?
Thanks in advance
