Backup transfer rate 29700 KB

[YANN1337]

Hi, I'm not a network specialist and I'm wondering if my backup transfer rate is good. The servers are VM's and like the Exchange and Database servers, has an NB Agent.

The backup goes on a RAID in the SAN at 29700 KB/s for the Exchange server and between 5000 to 20000 KB/s for the others servers.

I'm wondering if I have a good transfer rate

thanks

What's the total max, and total sustained (at peak load times, i.e. most backups running) aggregated ingest rate at the media server(s)?

Do you think you have a problem?

I have many backup clients run at those speeds.  The reason... individually they're slow, and there's nothing a "backup admin" can do about it usually.  But, when a backup admin has a hundred backup clients all each sending at 20000 KB/s - then a backup admin will usually start smiling.

Hi,

SDO is right. The speed of 30MB/s could be usually speed. So, is more steps for veryfing where is weak point of data transfer and follow more steps for increasing the speed. 

Example: Job detail information about buffer's delay should be first prompt .... see https://www.veritas.com/support/en_US/article.TECH145578

Backup speed is usually subjective.

When reporting backup performance issue, always look at these:

•  Data being backup (in size)
•  Number of files within the data 
         (Millions of files takes longer than thousands of them)
•  Backup speed  
         (Note, you should have at least one to compare with. Current job .vs. job in the past;  Current client .vs. another client backup by same media server in the same policy type etc.)
• Changes in your environment, such as network, OS, applications etc.

If possible, test with a normal file transfer (take backup software out of the equation) and see if you experience the same speed slowness.
