Do you mean is Flashbackup a separately licensed feature or do you mean is there another feature that can do this?

 

Cheers,

Thanks. I've not used Flashbackup before so I'll have to read about it. The utilization of the file systems I want to backup goes up and down drastically (in a day) but it still worth giving it a shot. Is there a separately licensed feature?

Khurram,

 

Flashbackup will improve the performance (it caches the data as a sort of snapshot then backs-up the snapshot so it's like a large file rather than loads of small ones, or something like that....) but because it works per volume, you need the space for the cache, which is at least the same size as the volume you are backing-up.

 

It will improve performance for loads of small files but probably won't help too much if they are on a huge volume and they take up a small % of the space.

 

Cheers,

Hi All,

We have just migrated to a NBU 6 SAN based environment. We have a server with a large number of small files (100k to 4MB) and its performing quite poorly on SAN based backup (5MB per stream). Can anyone advise some tuning parameters to  improve this speed? The library is L500 with FC LTO3 drives.

Regards,
Khurram
