CA ARCserve Central Protection Manager lets you specify the protection settings for the data that you want to back up.
To specify protection settings
The Policies screen opens.
The New Policy dialog opens, displaying the Protection Settings option of the Backup Settings tab.
You can specify a local path (volume or folder), or remote shared folder (or mapped drive) for the backup location.
For example, if you are attempting to back up your entire local computer which consists of Volumes C, D, and E; and also specify Volume E as your destination, CA ARCserve D2D backs up only Volumes C and D to Volume E. Data from Volume E is not included in the backup. If you want to back up all local volumes, specify a remote location for your destination.
Important! Verify that your specified destination volume does not contain system information or else it will not be protected (backed up) and your system will fail to recover after Bare Metal Recovery (BMR), if necessary.
Note: Dynamic disks cannot be restored at disk level. If your data is backed up to a volume on a dynamic disk, you cannot restore this dynamic disk during BMR.
You can specify to back up the entire computer or an individual volume on your computer.
Note: If the full machine backup option is selected, CA ARCserve D2D automatically discovers all disks/volumes attached to current machine, and include them in the backup.
For example, if a new disk is attached to the machine after the backup setting is configured, you will not need to change the backup settings and the data on the new disk will be protected automatically.
You also have the option to Select/Unselect all listed volumes.
Note: If some volumes are selected explicitly for backup, only the selected volumes are backed up.
A notification message is displayed for the following condition:
You can set the retention policy that is based on the number of recovery points to retain (merges sessions) or based on the number of recovery sets to retain (deletes recovery sets and disables infinite incrementals).
Default: Retain Recovery Points
Select this option to specify the number of recovery points (full, incremental, and verify backup images) to retain.
When the specified limit is exceeded; CA ARCserve D2D merges the earliest (oldest) incremental child backup into the parent backup to create a baseline image that includes the "parent plus oldest child" blocks. This cycle of merging the oldest child backup into the parent backup repeats for each subsequent backup, allowing you to perform infinite incremental backups, while maintaining the same retention count.
Note: If your destination does not have sufficient free space, consider reducing the number of saved recovery points.
Default: 31
Minimum: 1
Maximum: 1344
Note: When setting the time range to run the merge job, ensure that you specify a time range that will allow the related backup jobs to complete prior to the start of the merge.
Select this option to specify the number of recovery sets to retain. With this setting, you can disable infinite incremental backups forever, without merging any sessions. Using recovery sets helps resolve the time that it takes to complete merge jobs.
Select this option to specify the number of recovery sets retained. A recovery set is a series of backups, starting with a full backup, and then a number of incremental, verify, or full backups.
Example Set 1:
Example Set 2:
A full backup is required to start a new recovery set. The backup that starts the set is automatically converted to a full backup, even if no full backup is configured or scheduled to be performed at that time.
Note: An incomplete recovery set is not counted when calculating an existing recovery set. A recovery set is considered complete only when the starting backup of the next recovery set is created.
Default: 2
Minimum: 1
Maximum: 100
Note: When you want to delete a recovery set to save backup storage space, reduce the number of retained sets and CA ARCserve D2D automatically deletes the oldest recovery set. Do not attempt to delete the recovery set manually.
Example 1 - Recovery Set:
In this example, an incremental backup runs at 6:00 AM and 6:00 PM every day. The first recovery set is created when the first backup (must be a full backup) is taken. Then the first full backup is marked as the starting backup of the recovery set. When the backup scheduled at 6:00 PM on Friday is run, it converts to a full backup and the backup is marked as the starting backup of the recovery set.
Example 2 - Recovery Set:
Note: CA ARCserve D2D always keeps two sets so that one complete set is kept before starting the next recovery set.
Example 3 - Recovery Set:
Note: CA ARCserve D2D deletes the first recovery set when the fourth recovery set is about to start. Performing this action ensures that when the first backup is deleted and the fourth is starting, you still have two recovery sets (recovery set 2 and recovery set 3) available on the disk.
Even if you retain only one recovery set, you will need space for at least two full backups.
Note: The last backup may not be the last backup of the day when you run an ad-hoc backup.
Select this option to specify the type of compression that you want to use for backups.
Compression decreases your disk space usage, but also has an inverse impact on your backup speed due to the increased CPU usage.
The available compression options are as follows:
No compression is performed. This option has the lowest CPU usage (fastest speed), but also has the highest disk space usage for your backup image.
Some compression is performed. This option provides a good balance between CPU usage and disk space usage. This is the default setting.
Maximum compression is performed. This option provides the highest CPU usage (lowest speed), but also has the lowest disk space usage for your backup image.
Be aware of the following scenarios:
Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. CA ARCserve D2D data protection uses secure, AES (Advanced Encryption Standard) encryption algorithms to achieve maximum security and privacy of your specified data.
The available format options are No Encryption, AES-128, AES-192, and AES-256. (To disable encryption, select No Encryption).
For example, if you change the algorithm format and submit a customized incremental or verify backup manually, it automatically converts to a full backup.
For example, if you change the encryption password and submit a customized incremental or verify backup manually, it automatically converts to a full backup.
Note: Encryption settings do not have to remain the same for your backups. You can change these settings at any time, including after several backups of the same data.
You can specify the maximum speed (MB/min) at which backups will be written. You can throttle the backup speed to reduce CPU or network utilization. However, by limiting the backup speed, it will have an adverse affect on the backup window. As you lower the maximum backup speed it will increase the amount of time of perform the backup.
Note: By default, the Throttle Backup option is not enabled and backup speed is not being controlled.
The protection settings are saved.
