[gpfsug-discuss] backup and hsm with gpfs

[Stefan Fritzsche]

Dear gpfsug,

we are the SLUB, Saxon State and University Library Dresden.

Our goal is to build a long term preservation system. We use gpfs and a 
tsm with hsm integration to backup, migrate and distribute the data over 
two computing centers.
Currently, we are making backups with the normal tsm ba-client.
Our pre-/migration runs with the gpfs-policy engine to find all files 
that are in the state "rersistent" and match some additional rules.
After the scan, we create a filelist and premigrate the data with dsmmigfs.

The normal backup takes a long time for the scan of the whole 
gpfs-filesystem, so we are looking for a better way to perfom the backups.
I know that i can also use the policy engine to perfom the backup but my 
questions are:

How do I perform backups with gpfs?

Is there anyone who uses the mmbackup command or mmbackup in companies 
with snapshots?

Does anyone have any expirence in writing an application with gpfs-api 
and/or dmapi?

Thank you for your answers and proposals.

Best regards,
Stefan
