RISK vs REWARD or Small Additional Cost

#1

Post by armandh »

NAS4Free is, I note, usually called a stripped down FreeBSD dedicated NAS server

Yet there are those who would like to squeeze extra functionality out of a box they are leaving on anyway.
Not a bad goal, but at the risk of mucking up a very reliable data storage system, I question the merit.

I see a determination based on how valued is ones data.
if readily available from other sources shovel in the add on(s).
if the data is painful to replace, perhaps a separate box for the VOIP server is a better idea.

because I am risk adverse to putting all my data copies in one NAS,
I've gone in the opposite direction with two unadorned NAS,
and a P-4 spare ready to go, if needed.

I'm just not one for trying to turn a tow truck into a mini-van.
to me, such multitasking seems likely loaded with unintended consequences.
I don't want my data storage problems to resemble a comedic episode of top gear
after all, there is no shortage of extra hardware [or used mini vans]

I completely agree, though I wouldn't single out NAS4Free.
It's never a good idea to keep important data on a single machine, no matter how safe it's considered. I know of a guy who lost all of his family photos (and a bunch of other important data) because he tripped over and pushed his NAS off a desk.

The ideal backup solution (in my opinion) is the 321 system:
- 3 copies of any important file on at least
- 2 different kinds of media (or different machines) and
- 1 copy in an offsite location.
This way your data is safe no matter what.

Also, RAID isn't a backup.

I'm wrestling with the same dilemma. This is where I'm at:

1) Main Machine with all the taxes, photos, whatever - 3 disks in RAID 5
2) Backing up to NAS4Free with 2 disks in a ZFS mirror with Genie Timeline Pro (compressed and encrypted), wife's machine is doing the same
3) Rsync to a friend's machine over ssh

I really would like to get this all going under Tahoe-LAFS...

NAS-less for the moment

main machine is single Hdd with a secondary drive for quick back up
right now my off premise storage is limited to optical disk hand off
my two NAS are in the basement and running off the same UPS
this lack of physical separation is my biggest risk
I have Cu pairs to an adjacent structure but the [300m] distance limits it to 10T
unpleasantly slow compared to the house Gb lan

some of the newer 5Ghz WIFI may do the distance at the needed speeds
a dedicated WIFI link is something for me to look at in order to separate my NAS boxes
such separation would reduce the common disaster risk
at only the cost of lan hardware and the additional UPS

but for now the most important stuff gets a monthly hand-off
[only 88 Mb is so important to get this hand-off]
