If you're looking for something that will let you do more transactional
backups rather than a full DR then you might want to have a look at our
Dropbox app for IBM i. It's a free product that lets you move data
between your IBMi and Dropbox. We're currently connecting it with our
SAVE product that let's you do encrypted backups so you'll be able to
save and restore directly from Dropbox.

It's good to see we have considered the same issues as we talked here. We currently have around 750GB used space on a 1.2TB system. We do a full user library backup and a full IFS (we store scanned documents in the IFS) backup nightly. We do not do only changed objects. Makes restore so much easier. We do a full system save monthly. If we made this change I would still do the system save and have it local, off site in a vault. I would probably still keep a tape of the nightly backup locally for quick access for non-disaster restores and instead of driving the tapes to the vault daily, replicate the backup to the cloud.
Option 1 below sounds like what I was considering.

<Vendor Response>
At iInTheCloud.com we offer two cloud based backup options.
1- Back up to a local Crossroads SPHiNX VTL which is then replicated automatically to our SPHiNX.
- Advantage is fast backups with a local copy for fast restores.
- Automatic off-site copy as soon as the backup completes.
2- Use PowerHA or Mimix or MaxAva or ... to replicate data to a partition in our cloud. Backups are then done on our system and you have no outage whatever.
- Advantage is data is ALWAYS off site and current there.
- Advantage is bandwidth is much less as only changes cross the wire and they do so all day long as they occur.
- Disadvantage is a local restore is hard because the backups are with us!

Nathan's response pointed out one issue with backups to the cloud:
Bandwidth! You need a bunch in most cases unless you can really figure out what to back up each night. Change 1 row in a 500,000,000 row table and you get to send the entire table with that night's backup. If you were replicating to a remote server or partition ONLY that one change
goes across so its done instantly.
ALSO COnsider that until the ENTIRE backup has been copied off-site you got NOTHIN off site. Partial doesn't do you much good. With replication you're current off site almost continuously.
Just some points to ponder.....

Is anyone using cloud backup services for iSeries nightly backups? If you are how much data are you sending nightly and what service are you using?
