Once again, at this point in the operation, the backup application does not need the help of
ESE for a while. The backup application simply calls HrESERestoreOpenFile (ESE does
use this call to create the metadata needed for the restore.env file) for each log or
patch file to be restored and copies these files to the temporary directory specified at the
start of backup by the administrator (note that patch files are no longer used after Exchange
2000 SP2).
The log and patch files are copied to the temporary directory because of the requirement to
keep them separate from the log files in the production log file directory. This prevents
naming conflicts or overlaps between log files in the backup set and the log files on disk. The
best course is to copy the log files from the backup set to the temporary directory.
