5.1.8 Continuous Data Protection
Continuous data protection (CDP, but also may be called con inuous backup )
technology makes it possible to save data changes automatically and uninterruptedly,
restoring your data to its exact state at the moment of failure.
t
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.
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 Libraries and Autoloaders
A tape library is a high-capacity storage device consisting of one or more tape drives
and a loader, which automatically selects and loads multiple tape cartridges identified
with barcodes. Tape libraries having one drive and a loader are known as autoloaders.
Tape libraries are widely used as an efficient repository for long-term stored archival
data. Once the tape library is full, old data is progressively overwritten by new data.
With tape library support, Acronis Recovery for MS Exchange can store several backup
chains from different machines. Please review Acronis True Image Echo Enterprise
Server User’s Guide on how to backup to a tape drive in the network (section 3.8.3
“Setting up Backup to a Tape or a Tape Library in the Local Network” of the Echo
User’s Guide).
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 that is being backed up.
The locally connected tape drive will appear in the list of backup destination devices
along with other available drives. For instructions on how to enable backup to a tape
drive connected to a remote computer, see Acronis True Image Echo Enterprise Server
documentation section 3.8.3 “Setting up Backup to a Tape or a Tape Library in the
Local Network” of the User’s Guide.
