Compare the backup performance with different requirements using sample examples. We have observed the The 30x reduction in object count has been observed from the default block size resulted in an impressive a 3.5x performance improvement, considerably shortening the time to back up the files.
Sample Example 1
Using the 64KB Veeam default block sizes to backup the 10 VMs to a DataCore Swarm bucket results in a single 1.2TB job with the following Write/Read/Delete job times:
Job Type | Job Times | Average Speed |
|---|---|---|
Writing | 233 minutes | 77MB/s |
Reading | 121 minutes | 144 MB/s |
Deleting | 200 minutes | - |
The above test meets Veeam Certification requirements if the job completes in less than 270 minutes.

ImportantVeeam writes the backup data as 4,200,000 objects on DataCore Swarm. |
Sample Example 2
When Observe the following Write/Read/Delete job times when repeating the same test after increasing the Veeam object block size from 64 KB to 8MB, we observe the following Write/Read/Delete job times:
Job Type | Job Times | Average Speed |
|---|---|---|
Writing | 61 minutes | 288 MB/s |
Reading | 47 minutes | 372 MB/s |
Deleting | 11 minutes | - |
