Acronis Recovery for Microsoft Exchange - User Guide - Manual (Page 65)

Changing the restore process priority may have an adverse effect on the performance
of other programs running simultaneously. The priority of any process running in the
system determines the amount of CPU usage and system resources allocated to that
process.
8.4.3 Additional Settings
Backup archive validation
Before data is restored from the archive, Acronis Recovery for MS Exchange can check
its integrity. If you suspect that the archive might have been corrupted, select
Validate backup archive before restoration.
Overwriting mode
Enable Overwrite existing e-mails parameter to make Acronis Recovery for MS
Exchange overwrite existing e-mails with restored ones.
8.5 Acronis Active Restore or Dial Tone Recovery?
Acronis Recovery for MS Exchange allows a faster databases recovery using two
methods – Acronis Active Restore and dial tone mode. This section describes
differences and advantages of each method.
Using Acronis Active Restore
Acronis Active Restore acts the following way: after starting s restore task, a backed up
database is mounted directly from the archive. Then transaction logs, which are being
taken from the archive, will be applied. It is important, that database becomes
available for users after a short time – users can work with their folders, calendars, e-
mails. All other data is being restored from the archive in the background. After the
restore operation is completed, the database will be remounted, which takes less, than
a minute.
Please note, using Acronis Active Restore is inefficient if archives are located
on tapes or ftp servers – this operation may be time consuming.
