[gpfsug-discuss] Backup on object stores

Hi Matt,
With Spectrum Scale object storage, you can create storage policies, and
then assign containers to those policies.  Each policy will map to a GPFS
independent fileset.  That way, you can subdivide object storage and manage
different types of objects based on the type of data stored in the
container/storage policy (i.e., back up some types of object data nightly,
some weekly, some not at all).

Today, we don't have a cli to simplify to restoring individual objects.
But using commands like swift-get-nodes, you  can determine the filesystem
path to an object, and then restore only that item.

And if you are using storage policies with file & object access enabled,
you can access the object/files by file path directly.

Regards,
Bill Owen

Hello all,

Just brain storming here mainly but want to know how you are all
approaching this.  Do you replicate using GPFS and forget about backups?

This seems good for a full recovery but what if I just lost one object?
Seems if objectizer is in use then both tivoli and space management can
be used on the file.

Thanks in advance for your responses.

Matt
