Continuous Data Protection; Backing Up To Tape Libraries And Tape Drives - ACRONIS RECOVERY - FOR MICROSOFT EXCHANGE Manual

5.1.8 Continuous Data Protection

Continuous data protection (CDP, but also may be called
technology makes it possible to save data changes automatically and uninterruptedly,
restoring your data to its exact state at the moment of failure.
When you choose CDP technology during the creation of a backup task, you will have
to schedule only full backups. Acronis Recovery for MS Exchange controls folders with
archived logs and backs up all new logs into a CDP archive. A CDP archive contains a
set of full backups and an archive log, created after the last full backup. As a result,
you can restore data back to the last full backup, or to previously created archived log
backups, stored in the CDP archive.
When a new full backup is created, CDP logs will be truncated.
Please note, before starting any restore process, a CDP task must be stopped.
In case of restoring a whole database, a full backup must be created right
after the restoration process to protect your data.
A CDP task is processed in two ways: in a common task script and in a registry. The
registry's format is known only by CDP service (CDP agent). Thus, to change or delete
CDP task from Acronis Recovery for MS Exchange Management Console, you also need
a CDP service started.
Note, CDP technology cannot be used while backing up to tapes and FTP.

5.1.9 Backing up to Tape Libraries and Tape Drives

Acronis Recovery for MS Exchange supports tape libraries, autoloaders and SCSI tape
drives as storage devices.
Backing up to Tape Drives
SCSI tape drives are accessible both remotely using the Acronis ® Backup Server
(shipped with Acronis True Image Echo Enterprise Server) and locally when they are
connected to the computer where Microsoft Exchange Server is being backed up.
The locally connected tape drive will appear in the list of backup destination devices
along with other available drives.
To enable backup to a locally attached tape device with Acronis Recovery for MS
Exchange:
1. Attach the tape device to the computer.
2. Move cartridges from the Unrecognized or Import media pool to the Free pool
using the Removable storage snap-in (Control panel -> Administrative tools ->
Computer management -> Removable storage -> Media pools.)
3. If the tape contains data, its contents will be overwritten on prompt.
4. When creating a backup task, you will be able to select the tape device from the list
of destination devices.
5. For tape drives: As soon as the tape is full, a dialog window with a request to insert
a new tape will appear.
