MORE INFORMATION
================
Patch files (.pat files) are created when doing an online backup of the Exchange
databases. These temporary files get created as soon as the backup process
begins; they contain whatever transactions take place during the online backup.
This way the Edb.log can be copied during the backup while transactions are
written to the patch files. The *.pat files are also copied to the hard disk
drive and replayed when a restore is done.
It is safe to delete these patch files if these two conditions apply:
- There is no backup taking place.
- There is no startup recovery in process after a restore.
