Disclaimer: Backups were performed using PowerScale storage as the source and PowerProtect DD series as the backup target with PowerProtect Data Manager. These results were derived from Dell Technologies internal testing performed under varying conditions.
Filesystems come in all sorts of complex topologies. In this section, we observe the average write throughput achieved during backups for file systems with Balanced directory structure and Unbalanced directory structure. Data Manager uses auto slicing and intelligent scaling through proxies to support faster multistream backups irrespective of the file system type.
With a Balanced directory structure (millions of 512 KB files distributed in multiple directories), the initial full backup to PowerProtect DD series is completed with a write throughput of 4 TB/hr. A subsequent incremental backup (with 4 percent change in data) shows an increased throughput of 5 TB/hr.
Comparable results are seen with an Unbalanced directory structure as well (millions of files varying from 32 KB to 4 GB file sizes distributed in multiple directories). During an initial full backup to PowerProtect DD series, write throughput is 2 TB/hr and the incremental backup (with 4 percent change in data) shows an increased throughput of 3 TB/hr.
For these tests, multiple proxy engines were used to support the workload, and the asset level parallelism was set to 256. To learn more about calculating number of proxies required and setting protection engine parameters, see Sizing recommendationsSizing recommendations.
