Which is what my current choice, CrashPlan, is doing at least to consumers.
They are at least staying in business, so my current subscription will last until - with an extra 60 days - July next year.
The two options they're suggesting are
a) Migrating to what they used to call CrashPlan Pro and are now going to call CrashPlan for Small Business. With 75% off for the first year after the current sub expires, that is quite reasonable.. at first. It'll be cheaper (12 x $2.50 < $59.99) until it gets to 2019 when the price will be at least $120, i.e. double what I am currently paying.
b) Using Carbonite. Fuck off, for the reasons given in the earlier post.
Of the ones other people use, Backblaze still doesn't do Linux* and SpiderOak is still $129 annually if you have less than 1TB of data and HOW MUCH (in this case, $279 a year) if you have more (but not more than 5TB). Plus Amazon AWS are still doing a pricing scheme that makes it clear that they're not interested in consumers.
Annoyingly, Amazon Digital Music Storage wants you to install a Windows or Mac program to do the uploading for its '250,000 files for - I think - £22/year', so I am less tempted than I otherwise would be to see if it accepts really, really, really long metadata (the ID3v2 standard allows up to 256MB!) for .mp3 files :)
It does remind me that when Napster was a new thing, someone did a Windows program 'Wrapster' that made any file look like an .mp3 file so it could be shared. I wonder if there was ever a Linux equivalent? Or given that I'm pretty sure I have a copy, somewhere, I wonder if it works under WINE?
But without playing around like that, it's looking like I will go to CrashPlan Pro, but possibly only until 2019.
* And if CrashPlan are doing this, I would want to have a look at Backblaze's accounts before believing that they're not going to be next.
