Re: disaster recovery log file question

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

This is an exchange 2000 box so i dont have a RSG. I do have copies of the
databases and logfiles at the point of both failures though, so i may be
able to do something..
If i use the copy of the first one that failed. That still works and the log
files from the second one that should work?

Hello all,

We recently had an exchange failure here due to faulty drives. We were
temporarily able to get the failed server online before it failed again
with
the replacement drives failing! during the second failure the database
was
corrupted and i am unable to repair it. We successfully restored from
backup and server is running fine now. My question is regarding the mail
t
hat came in while the server was temporarily back online. I still have
the
transaction logs that were not committed to the database yet. (it failed
before a backup could complete) Is it possible for me to somehow roll
them
into the working database and recover the mail?

Transaction logs are not committed during a backup, they are committed
continuously while the store is mounted and running. An exchange aware
backup *purges* the logs that have been committed to the store.

As far as replaying logs, The time to replay them would have been the
restore ( assuming you had them all without any gaps)
Now that the store is mounted, they wont do you any good.

But..... If you can restore the previous backup to the recovery
storage group and can copy all those transaction logs into the RSG
directory ( and again no missing ones), the restore will bring you up
to the point of failure. You can then use exmerge or the built MAil
Merge Wizard in Exch 2003 to add back any missing messages to the
mailboxes.

Thanks Andy
