If you are not using HSM, the virtual mountpoint approach is a good
one. Since we do have an integrated TSM/HSM system on GPFS, we
can't do that. It takes a bit over 3 days to wade through 130+
million files. Not enough disk to use mmbackup, which basically
'journals' the changes. I do run incrementals on directories 
that are critical while the overall incremental runs.

What version of GPFS and TSM are you using? We are a bit backlevel
at GPFS 3.3 and TSM 5.5, but are in the process of upgrading. I
think a more current combination will allow for faster backups.

Is it organized into subdirectory trees?  If so, virtual mountpoints might be a 
way to go.

Hi everybody,

Does anyone know what is the best way to make a filesystem backup than contains 
million files?

Backup image is not posible because is a GPFS filesystem and is not supported.

Thanks in advance

Jorge
