Specify Advanced Backup Settings

CA ARCserve Central Protection Manager lets you specify advanced settings for your backups.

To specify advanced backup settings

1. From the CA ARCserve Central Protection Manager home page, click Policies on the Navigation bar.

   The Policies screen opens.

2. Click New to create a new policy.

   The New Policy dialog opens.

3. Click the Advanced tab.

   The Advanced Settings options dialog opens.

4. Specify the advanced actions setting options.
   • Truncate Log--Specifies to truncate the accumulated transaction log files for the selected applications after the next successful backup.

     CA ARCserve D2D backups consist of a snapshot image and the transaction log files that were created for it. At some point in time, the older (committed) transaction log files are no longer needed and can be purged to make space for new log files. The process of purging these log files is called truncating the log. This option enables truncating of committed transaction log files, which conserves disk space.

     The available options are SQL Server and Exchange Server. You can select either, both, or none of these applications. If you select any of these applications, you can also specify a scheduled time period (Daily, Weekly, or Monthly) for automatic log truncation:

     Note: The transaction log files cannot be truncated without performing a successful backup.

     • Daily--Each day after the backup completes successfully, the committed transaction logs will be purged immediately.
     • Weekly--After seven days, the committed transaction logs will be purged immediately after the backup completes successfully.
     • Monthly--After 30 days, the committed transaction logs will be purged immediately after the backup completes successfully.

     If a backup job is already running at the same time the purging is scheduled to be performed, the purging operation is moved to the next scheduled job.

     For Example:

     If you scheduled an Incremental Backup to run automatically every day at 5:00 pm, and start a Full Backup manually at 4:55 pm, then assume that the backup successfully finishes at 5:10 pm.

     In this case, the Incremental Backup that was scheduled for 5:00 pm will not run because the ad-hoc Full Backup is still in progress. Now the committed transaction log files will be purged after the next successful backup job. In this case it will be performed on the next day after the scheduled Incremental Backup completes successfully at 5:00 pm.

   • Reserve Space on Destination

     This value indicates a percentage of the calculated space that is necessary to perform a backup. This amount of continuous space is then immediately reserved on the destination before the backup starts writing data and helps improve backup speed.

     Default: 10%.

     Example: Set the value to 10% and the current backup has 50 GB of data to back up. Before the backup starts writing data, it first reserves 5 GB of disk space. After the 5 GB of disk space is used up, it then reserves the next 5 GB of disk space. If the data remaining for the backup is less than 5 GB (suppose 2 GB are remaining to back up), then the remaining GB (in this example 2 GB) are reserved.

   • Catalogs

     Exchange Granular Restore Catalog

     When this option is selected, enables automatic generation of the Exchange Granular Restore catalogs after each backup. By default, this option is enabled.

     An Exchange Granular Restore backup captures information about the mail message, the mail folder, and the mailbox levels of Exchange in a single pass backup through the Exchange database. With this option enabled, you can then perform granular recoveries of the Exchange database by selecting from a list of objects inside Exchange and specifying exactly what you want to recover without first having to recover or dump the Exchange database to an alternate location.

     Advantages: With an Exchange Granular Restore catalog, there is no need to wait a long time to perform a restore browse.

     Disadvantages: When you generate an Exchange Granular Restore catalog during each backup, it results in an increased backup window (additional time to complete the backup job) and an increased workload. CA ARCserve D2D must go to each mailbox, authenticate, and build the granular information, which considering the number of mailboxes and size of data, could be a time consuming task.

     Note: If you disable this option, CA ARCserve D2D only saves the general information for Exchange. Before restore you have an opportunity to generate an Exchange Granular Restore catalog at that time.

     File System Catalog

     When this option is selected, enables generation of the file system catalog. If your browse time is too slow (especially if the CA ARCserve D2D destination is over a WAN) or if your restore by search time is too slow, this option helps reduce your wait time. This catalog job will run for each scheduled backup job after this option is selected.

     If this option is not selected, the restores can be performed immediately after backup without having to wait for the catalog job to finish. By default, this option is not enabled.

     Note: When you generate a File System catalog for each backup job, it results in an increased amount of disk storage needed to store the metadata files and catalog files and an increase in CPU usage. In addition, if the backup source contains a large amount of files, the process of generating a catalog could be a time consuming task.

   • Administrator Account--Specifies the User Name and Password with access rights to perform the backup. CA ARCserve D2D verifies that the name and password are valid and that the user belongs to an administrator group.

     Be aware of the following:

     • To specify a domain account, the format for user name is a fully qualified domain user name in the form of "<domain name>\<user name>".
     • If the Administrator Account information for the CA ARCserve D2D server is changed (User Name/Password), then reconfiguring the Administrator Account information from this dialog is recommended.
     • If you do not specify the Administrator Account credentials, then CA ARCserve D2D automatically enters the account information where the policy is deployed to.
5. Click Save.

The advanced backup settings are saved.
