the impression i got from people here, was that crashplan was offering unlimited backups/storage…
can you pass us some more info on your situation/costs involved?
if you still have about 500gb of data used, (estimated at 750gb?) have you looked at the 2 new products from drobo’s sister company (or parent company now), called Transporter and Transporter sync?
If it’s just data you need to backup, it might be a cheap way (one time cost outlay) to get one and plug in a 1tb drive for example, and to have all your data synced to there. (but, you would have to trust the Off site location, such as good friend or relative etc, and you “might” have to give them a little something towards energy bill) but it might be worth it over the years.
in one of your other posts, you mentioned a worry about fancy drive images failing to restore.
(this is a Valid concern, and the closest thing i know that supposedly still restores for you, is Acronis)
i’ve only tested out an acronis from a 500gb drive, onto a 1tb drive on the same machine, but the version i bought is supposed to let you restore to any other hardware…i just havent had the pleasure/reason/time to test that part out yet though
