Full and Incremental backups are the only type of backups that purge the
transaction logs.
As for brick level backups, my personal opinion of them is that they're
a horrible kludge.  As Ed Crowley puts it, they're intended for people
who insist on managing their environment as if it was MSMail.  :0)
Implement deleted item and deleted mailbox recovery, and you'll probably
never need a brick backup.  They take ages to process, and are prone to
errors as you've seen.  Usually benign errors, though.
You should be doing a full online backup of your storage group object,
and as long as you're also backing up your system state, etc, you should
be good to recover.

We use Arcserve 2000 Advanced Edition with the Exchange backup agent on
an Exchange 2K Server w/ all SP's. We do a full weekly backup with daily
differentials. This is a brick backup. My question is for anyone who may
do a similar backup.
After the full backup, the logs are deleted, as they should be, but on
the daily differential backup, they are not. I've gone over the Arcserve
backup logs, and the only "errors" are for those mailboxes Exchange
couldn't backup. These errors change daily (different people, different
folders) Last night there were 15 "failed to open store" errors out of
the 1250 mailboxes backed up. Is this what is causing the logs not to be
On a similar note, Is doing a brick backup the best choice, or should I
just do an Exchange backup, and skip the brick?
