Make sure your plan includes storing at least some of the backups
off-site, to protect against disasters such as fire or tornadoes. Also,
make sure your backup plans include periodically checking that the data
backed up is usable. Back in my system administration days, I once
encountered a situation where a hard drive problem was garbling the data
before it was backed up; the backup software wasn't reporting any
problems, because it was making an accurate copy of the already-garbled
data.

I really can't help on the storage side but that article should give
you an idea on hard drive reliability. Unless you want to replace ALL
the data when any single drive fails I'd recommend some form of
redundancy. Depending on how deep you want to go down this rabbit
hole, take a look at ZFS on Linux.

Hello NLUG,
Thanks to Jerry Perkins (for invaluable guidance on installing
Debian server) and thanks to NLUG we are getting a direly needed
backup / archive system in place. I'll let Jerry share his
meticulous notes on the details. Interestingly, due to
transportation issues, Jerry has been guiding me via phone and
email, so I am seeing all the details, that I might not otherwise
see if he were present doing all the implementing.
For the archive portion of the project (190TB of video, growing by
2TB per month), I was thinking of a JBOD array (or multiple lesser
arrays). I've been advised against RAID, as this won't be the
only existing archive and due to length of time for RAID rebuild
in the event of a drive failure.
At our December meeting Vince mentioned something important if not
critical to consider, that we may see a flood of cheaper HDDs hit
the market. Indeed, Seagate's former 5yr warranty is no longer;
now it's one year.
We currently put to use a Dell R220 with miniSAS, USB3, and dual
ethernet ports; maybe I should add eSATA? I know that some of you
having worked at DELL don't hold their hardware in high regard;
this was just bought a while back (for an LTO6 system still to be
implemented... later)
Anyone with knowledge and experience on different HDD array
hardware, please advise.
This help is saving us thousands of dollars in (in$ulting) IT
con$ulting.
Thank you kindly- M
PS I can still come video the meetings - just have to bolt at
7:02pm - anything to help keep NLUG going. I'd be drowning
without it.
