Jorge,

On Unix systems:
I've done it in two steps.  Create a tar file of the file system and zip
it.  Create a second file listing all the files in the tarred directory.
The tar extract command allows single files to be recalled if the
absolute path name is available.

I've used this to backup a Sterling Commerce flat file database with
multiple subdirectories holding more than 1.5 million files.  The
tar/gzip command took 5 or 6 hours for a 500 GB file system.  

I have not tried to do this on a Windows system.

Subject: [ADSM-L] million files backup

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
