Hello,
Looking for someone who has done this before.  I had a nasty sbs 2003 crash where both my backup methods failed.  I was able to do a full restore but back to a state as of 2 months ago.   I was doing this remotely from vacation overseas with some IT help.  Now that i am back, I am able to boot the crashed server off a boot cd with raid drivers loaded.  I am copying the exchange folder (MDB's and transactions logs dating back to 2 months ago when the last backup ran).   I think there is a way I can restore this?  Do I just replace the exchange folder structure or is there a way to replay the logs back into the current exchange database (which in its current state is 2 months old).  I have the Information Store service turned off for now until I figure this out correctly.

Also the 2 month old restore was done with a BDR baremetal restore which worked great, it is just old.

If you have the full transaction logs for the last 2 months, then copy it into the transaction logs folder for that storage group.

In most cases, the best way to run soft recovery is to mount any database in a storage group. Because all databases in a storage group share a single stream of log files, soft recovery occurs at the level of the entire storage group and not at the level of the individual database.

In some special circumstances, there are advantages to running soft recovery using Eseutil.exe. The most common scenarios are:

    * You want to recover a storage group that has a missing database.
    * You want to recover an individual database "out of place" without affecting other databases or the storage group's log files.

The complete syntax for the Eseutil.exe soft recovery function, listing all possible switches, is:

ESEUTIL /r enn /L[path to log files] /s[path to checkpoint file] /d[path to database file] /i

Shaba,
Thanks for the response.    To clarify:
* My current exchange 2003 information store (only the 1default storage group) has pub1.edp and priv1.edb from 2 months ago.
*I have been able to copy (to usb drive) the whole \exchsrvr folder from 3 days ago (day of crash) which included the MDBDATA subfolder which has the most recent pub1.ebp and priv1.edb + a ton of transaction log files.
STEPS TO RESTORE:
1. copy \exchsrvr\mdbdata\*.log to the current information store location \exchsrvr\mdbdata
2. do I also copy the *.edb and *.stm or just the *.log files?
3. Then start information store and all associated exchange services and test it out.

Is that right?   I doesn't look like I will need eseutil as this is just a simple db.
If so, this would be SUPER helpful as I can do this without bringing down the server and can do it this morning.
Thanks,
Berne
