snapshot and periodical backups
And instead of connecting the snapshots to a particular machine, it would be nice to be able to buy a block of storage and backup any of our machines into it without having to worry about it going away if a specific machine is removed.
Slicehost (where I moved from) binds the snapshots to the machine it was created from, so if you delete the Slice, you lost your backups of it. It would be better to have it independent, then user's could pre-build custom machines, back them up them and have them ready for deployment at any time.
I know your linode guys are still working on this.
But it would be better if you can offer an estimated date.
