I've been wondering this as well.
My home backups are somewhat large and not yet offsite due to their =
size. (~4.7TB).
This is due to both purchased digital media storage and photography. =
These are sufficiently large that the problem is harder to resolve, as =
nobody "makes" a 5TB drive I can ship to a colo. Drive failures in the =
"backups" host also become painful to work with as I'm cheap so the ZFS =
pool isn't 100% mirrored.
Some machines use netatalk plus the "defaults write =
com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1" hack.
I've considered just subbing to backblaze as it's "cheap" on a =
single-host basis, but need something closer to ~5-7TB plus some room =
for growth (maybe 250G-500G/year). I have considered just trenching =
copper/fiber (see other thread) to a neighbor and placing the host =
there, but it's not much geographical diversity, plus if the neighbor =
moves it becomes fun to re-explain what you are doing. (worse if they're =
non-techie).
The biggest problem I've seen is with a "cloud"/"tubes" provider, my =
upload speed puts the 4.7TB initial sync somewhere around 145 days =
(assuming 3Mb/s upload).
Is anyone aware of a solution for this that is sensible $$$ without =
rolling my own (i'm estimating about 2-3k to do this...)? And =
preferably costs maybe $ or $$?
