I've just checked with linode - the backup price is shifting too, so the cost will not increase. They have not updated their FAQ yet.
--------------- Hello,
The backup prices are shifting just as the RAM prices shifted, so Linode 1GB backups are now $5, Linode 2GB is $10, and so on.
I hope this clears things up. Please let us know if we can be of further assistance.
Regards, Jonathan --------------
I just checked with Linode support, and their backup pricing will be adjusted to match with the old rates as well. So if you’ve been paying $5/month for backup service, your price will stay the same post-migration.
This RAM change is now reflected here. http://www.linode.com/backups/
I'm sure it's a good deal all around, but it seems like a slight of hand to me: Linode, now with more RAM, AND more expansive backups for the same disk space.
