Tuning vaulting attributes on the backup system

Note: These steps can be run as a standalone procedure or as part of a larger process. For an overview of the process, see Vaulting setup.

Once the local backup system is added to the vault, vaulting configuration is almost complete. You can now tune the backup system to perform optimally given the available bandwidth. You can also configure the amount of data that can be vaulted and other attributes.

To set the vaulting attributes on the backup system

This procedure can be run from the backup system or vault.

Select the backup system in the Navigation pane and click Replication > Replication Attributes.

Select Bandwidth and Throttling Options and configure the following:

•

Connection Type – The connection’s theoretical physical bandwidth. If your specific connection is not in the list, pick the closest upstream bandwidth match.

•

Connection Effective Bandwidth – What you expect the actual bandwidth of the physical connection to be.

•

Throttling Settings – Use the grid to configure settings.

Throttling is simply the act of responsibly sharing the bandwidth of the WAN by which the Unitrends vault provides disaster recovery services. Set the weekly vaulting schedule using the graphical tool consisting of 7x24 small boxes that represent each hour of the week. Click and drag to select multiple boxes.

Multiple throttling scenarios can be configured. Select the throttle percentage, then click and drag the mouse pointer to highlight the days and times to use the selected percentage. Perform this step as many times as needed to fully configure throttling scenarios. The percentage you select uses X percent of the Connection Effective Bandwidth you set above for vaulting.

Select Connection Options and Process Control and configure the following:

•

Transport Type – The transport type that should be used to sync data. Select ssh or socket. The transport type should only be set to socket when the connection between the system and the vault is secured by some other means, such as a VPN.

•

Poll Frequency – The number of minutes between synchronizations. Select the interval at which the system checks for new backups to vault, in minutes. For example, when set to 30, the application scans for data to be vaulted every 30 minutes.

•

Retries – The number of times a vault job will be retried before declaring a failure and moving to the next one in the queue. A job that cannot vault is moved to the bottom of the queue after n retries, where n is the number you specify. If retries is set to zero, each failed attempt will log a failure. If retries is set to a non-zero number, vaulting of a backup would need to fail that number of times plus one, before a vaulting failure is logged. For example, if retries is set to three, vaulting operations have to fail four times before the failure is logged.

•

Maximum Space – The maximum allowable amount of disk space consumed by delta files on the system. When vaulting is initiated, a sum of all the delta files that exist on the system is determined and rounded up to the nearest GB. If that sum equals or exceeds the maximum space, vaulting then skips any sync operation that involves creating another delta file.

•

Vaulting Deduplication On – Check this box to enable deduplication. When deduplication is not enabled, backups are copied to the vault in full. This should only be done when the backup system and the vault are on the same network and there is a large amount of bandwidth over which data can be transferred.

•

Resume/Suspend Vaulting – Select to resume or suspend vaulting operations. For initial configuration, click Resume Vaulting to enable the vaulting process.

If suspending vaulting, an option is presented to suspend vaulting immediately by selecting Yes, or suspend it after any vaulting operations in progress have completed by selecting No. If you suspend immediately, vaulting operations in progress are stopped. Selecting Cancel takes you back to the previous screen, and vaulting continues without interruption.

Note: Suspending pauses vault operations temporarily, until you click Resume Vaulting. It does not remove the vaulting configuration.

•

Reset Vaulting – Stops all in-progress vaulting operations immediately and then restarts vaulting.

Select Report Options and configure the report email address and the time at which vaulting reports will be sent.

Select Local Directory Options to configure vaulting of the backup system’s local directories, if desired.

Vaulting can be used to provide disaster recovery for any set of local directories on the on-premise backup system. Check the Vault Local Directory Information box and add directories to protect via the vault. Click Open File Browser to browse for directories.

Select Baremetal and Application Options and configure the following optional settings as desired:

•

Check Vault BareMetal Backups to vault bare metals.

•

Check Vault Legacy SQL Server Backups to vault backups of SQL Server 2000 databases.

•

Check Vault Legacy Exchange Backups to vault backups of Exchange Server 2000 stores.

If legacy Exchange backups (pre-4.2) are to be vaulted, you must specify the directories associated with Exchange. Legacy Exchange backups are stored in the following directory:

/backups/samba/<name_supplied_during_configuration>

For information on the granular selection of items associated with the vaulting of specific applications or virtual machines, see To vault application backups.

Once vaulting process configuration is complete, select Confirm to save all changes.

Proceed to Configuring clients for vaulting to continue vaulting setup.
