5 Setting up the DR Series system cleaner Performing scheduled disk space reclamation operations are recommended as a method for recovering disk space from system containers in which files were deleted as a result of deduplication. The system cleaner runs during idle time. If your workflow does not have a sufficient amount of idle time on a daily basis, then you should consider scheduling the cleaner to force it to run during a scheduled time.
6 Monitoring deduplication, compression, and performance After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the DR Series system dashboard. This information is valuable in understanding the benefits of the DR Series system. Note: Deduplication ratios increase over time. It is not uncommon to see a 2-4x reduction (25-50% total savings) on the initial backup. As additional full backup jobs are completed, the ratios will increase.
A Setting data expiration for Backup Exec 2012/2014/2015 Backup images are deleted by Backup Exec after image expiration if more backups have run (At least two full backups of the same data set). Refer to the following article for more information: http://www.symantec.com/business/support/index?page=content&id=TECH187957 For more information about image expiration, refer to the Backup Exec 2012 Administration Guide chapter, “About Backup Job Settings.
B Installing Backup Exec Agent on Linux client (RALUS) Detailed information is available at following Symantec’s link – http://www.symantec.
C VTL configuration guidelines C.1 Installing latest Backup Exec service packs for the DR Series system iSCSI VTL capability The following Service Pack 2 from Symantec is required on the Backup Exec 2014 Server for smooth integration between Dell DR’s iSCSI-VTL and the BE server: Backup Exec 2014 revision 1786 Service Pack 2 Backup Exec 2015 server by default supports the Dell DR Series system iSCSI-VTL capability. C.2 Managing VTL media and space use C.2.
Various factors such as total data footprint, change rate, backup frequency and data lifecycle policies will dictate how much physical space will be needed to accommodate the Virtual Tape Libraries within a DR Series environment. In addition, if other container types are hosted these two must be factored into space requirement calculations. As a general rule the following can be used as a reference architecture to determine the basic capacity needed for a given virtual tape library container: 1. 2. 3. 4.
In the previous example at the end of the 5-week cycle the 1st week retires and frees up media to be reused or recycled which once processed will allow the DR to reclaim the physical space associated with the virtual media. Since the smallest data set footprint resulting from the change rate is 2TB in each incremental iteration we create our media at 800GB increments and add as we grow.
Type Capacity Max number of Tapes supported LTO-2 200GiB 8000 LTO-1 100Gib 10000 LTO-1 50Gib 10000 LTO-1 10GiB 10000 Note: With a VTL container, it is very easy to add additional tapes as and when required. It is recommended to add tapes in the increments of 50 and 100 to facilitate easy inventory from Backup Exec. Check the Backup Exec recommendations for the maximum number of tapes supported.
