fbackup too slow

[Rommel T. Misa_2]

Hi guys,

I'm experiencing slow filesystem backup using fbackup. We're backing up 17 GB of data but 2 hours have passed and still it's not yet finished. How can I tune fbackup for it to run faster?

Thanks.

Hi,

Have a look at this doc from the ITRC tech database.

Backing up a large amount of data that consists of a few big files may have less system overhead than backing up a large number of small files. If a file system contains millions of small files, the very nature of searching the file system structures for changed files can take hours, since the entire file structure is searched

Hi Rommel,
Are you backing up on a Tape or a Disk?
If you are backing up on a tape. Please see the following threads and the possibility for the problem you are experiencing.
Please replace the cable going to the tape - (

and check if that made any difference ?

Also please see if the Volumes that you are backing up are having any high disk activity.

Is Fbackup slow always or only during a certain point of time?
