Out on the HP 3000 Community of LinkedIn, managers have been apprised this spring of an offering from Beechglen Development called Triple Store. The essence of the advice is sound. Make multiple backups, because it's risky to rely on just one tape -- and too time-consuming to simply make multiple tapes.

Triple Store proposes a primary copy goes to local user volume storage on your 3000. The secondary local copy goes out to a Linux Appliance, as Beechglen calls it. There's a third copy that goes into SSD storage in a cloud which Beechglen hosts offsite.
You can look over the pricing in a single-page datasheet from Beechglen, but it's that Linux Appliance that might be the newest wrinkle in a multi-copy strategy. This particular application encrypts the backup and applies compression. Secure FTP (SFTP) can pass the backups from standard HP 3000 73GB user volumes to this Appliance. For those who unfamilar with the appliance concept, it is a separate server powered by Linux and loaded with an application dedicated to backups.
Brian Edminster, our backup advisor for 3000 operations, keyed in on the Triple Store's appliance, too.
The greatest novelty is having a Linux-driven appliance to act as a secure intermediary. It appears to be to sending backups ultimately to one's own Network Attached Storage (NAS), off to Beechglen's cloud, or onto SSDs (which are being used as the removeable media). I already do backups for the systems I administer in a similar way.
Edminster said that he does a Store-To-Disk, usually to a separate user volume dedicated to holding backups; then he does an FTP or SFTP of this disk-backup to a NAS device, "where it's backed up by an enterprise backup tool."
Not addressed -- but implied in the marketing piece for Triple Store -- is the mechanism for recovering a backup from the backup appliance archive (or from SSD or cloud to the appliance, and then to your 3000).
Sure, you can just FTP/SFTP it back to the 3000's file system, should you need a backup image that's no longer on your user volume. The problem seems to be that won't preserve the MPE-ness of the Store-To-Disk backup files. Unless you take special steps, you might lose the MPE/iX filesystem characteristics of the backup -- making it difficult to restore from without additional processing. Not good.
I've been looking into simple ways to do this (preferably an FOS-only solution), and have been experimenting with a number of methods.
In the weeks to come, we’ll look forward to a report from Edminster on how to do this sort of multiple store using a limited amount of non-MPE software.
