Re: [gpfsug-discuss] Snapshots for backups

[Andrew Beattie]

Hi Jonathan,

 

First off a couple of questions:

 

1) your using Scale+Protect with Tape today?

2) your new filesystems will be within the same cluster ?

3) What capacity are the new filesystems

 

Based on the above then:

 

AFM-DR will give you the Replication that you are talking about -- please talk to your local IBM people about the limitations of AFM-DR to ensure it will work for your use case

Scale supports snapshots - but as mentioned snapshots are not a backup of your filesystem - if you snapshot corrupt data you will replicate that to the DR location

 

If you are going to spin up new infrastructure in a DR location have you considered looking at an object store and using your existing Protect environment to allow you to Protect environment to HSM out to a Disk basked object storage pool distributed over disparate geographic locations? (obviously capacity dependent)

We are looking at standing up some new filesystems and management would like us to investigate alternative options to Scale+Protect.  In particular, they are interested in the following:

 

Replicate to a remote filesystem (I assume this is best done via AFM).

Take periodic (probably daily) snapshots at the remote site.

 

The thought here is that this gives us the ability to restore data more quickly than we could with tape and also gives us a DR system in the event of a failure at the primary site.  Does anyone have experience with this kind of setup?  I know this is a solution that will require a fair amount of scripting and some cron jobs, both of which will introduce a level of human error.  Are there any other gotchas we should be aware of?
