[gpfsug-discuss] backup and disaster recovery solutions

[Marc A Kaplan]

Since you write " so if the file is not touched for number of days, it's 
moved to a tape" -
that is what we call the HSM feature.  This is additional function beyond 
backup.  IBM has two implementations. 

(1)  TSM/HSM now called IBM Spectrum Protect.

(2) HPSS http://www.hpss-collaboration.org/

The GPFS (Spectrum Scale File System) policy feature supports both, so 
that mmapplypolicy and GPFS policy rules can be used to perform
accelerated metadata scans to identify which files should be migrated.

Also, GPFS supports on-demand recall (on application reads) of data from 
long term storage (tape) to GPFS storage (disk or SSD).  See also DMAPI.

We have implemented 1.5PB ESS solution recently in our HPC environment. 
Today we are kicking of backup and disaster recovery discussions so I was 
wondering what everyone else is using for their backup?

In our old storage environment we simply rsync-ed home and software 
directories and projects were not backed up. 

With ESS we are looking for more of a GPFS based backup solution - 
something to tape possibly and also something that will have life cycle 
feature - so if the file is not touched for number of days, it's moved to 
a tape (something like LTFS).

Thanks in advance.
