low speed when backup many small files
Environment

Hello All
We have one policy with standart type which is backing up file system,
It starts appr. 60 MB/s. when the backup process reach to the path which are located many small files the speed decreasing till 2 MB/s.
How to solve this issue??

I agree with Nicolai - quite normal...
How long does it take to run 'ls -lR' against this filesystem?
NBU (bpbkar) needs to do the same in addition to reading each file in order to backup it up.The alternative is to see if FlashBackup is an option.
Compatibility Guide over here: http://www.symantec.com/docs/TECH126901Or else multi-streaming as per Nicolai's suggestion:
NEW_STREAM
/big-volume1/folder1
/big-volume1/folder2
NEW_STREAM
/big-volume1/folder3
/big-volume1/folder4
NEW_STREAM
/big-volume1/folder5
