Setting up a 20TB backup drive for Power7+ Published by: Bob Cozzi on 08 Jul 2014 view comments(3)

Arriving today is a NAS that will have about 20TB capacity. I'm going to set up nightly FTP transfers of *SAVF files from the IBM i partition over to these drives and use them as backup. I've been desiring this kind of thing for a while, but capacity and cost have just come into line with what's practical. The drives are RAID'd and in another physical location, and I don't really care how long the transfer takes, but it shouldn't be too bad at 100MBs LAN speeds. (Yes we have a GB LAN but the weakest link is a 100MB CiSCO ASA).

I want to do this for a client as well, but outbound T1 lines or cable connectivity can take "centuries" even at 10MB (most are 1.5 to 3.0 MB). So I don't think the networking has come into play yet.

What are you doing for off-site backups?

Our entire machine is hosted at a collocation facility along with the backups, etc.

You say that it is at another location, so I assume you have a vpn between the two, rated at 100mb's? Just because your lan speed or your router is 100mb, if you don't have the pipe size between the two and don't forget the encrypting and decrypting of the vpn traffic will way heavy on this process.

Also, hopefully you won't end up with an issue with files over 4gb in size, which can sometimes be a windows issue, depending on the software on the NAS.  Is the nas running a program to suck it off like batch synch ftp or you pushing it from the ibmi?

Of course if you deal with credit cards or probably hippa, etc. all sorts of red tape for that nas.

They just ferry tapes via courier.

How far away is your other location, and do you have line of sight? Microwave could be an option.
