[Box Backup] Box Backup status

No such feature is "planned" (i.e. scheduled for implementation), although 
I for one agree that it would be very useful and important, and I might 
implement it myself if Ben doesn't veto it.

IIRC, his objection was that it's impossible to unit test every case of 
client vs server versions. Just testing one version of the client with the 
server is hard enough.

I agree with this, but I think that as part of an upgrade process, people 
should be able to move smoothly from a supported pair (0.09 
clients+server) to another supported pair (0.10 clients+server) via an 
unsupported pair (0.09 clients + 0.10 server), on the understanding that 
this unsupported state is much less reliable and tested, and therefore 
only temporary and to be exited as soon as possible.

This could perhaps be encouraged by an options such as 
"EnableDangerousBackwardsCompatibility = yes" in the store configuration 
file.

I also think that it would be possible to test 0.10 server + 0.09 clients, 
by adapting the current unit tests, although it would be quite messy.

As far as I know, only the open tickets at 
[http://bbdev.fluffy.co.uk/trac/report/1] are being actively worked on. 
Some of these will make it into the next planned version, 0.11, which will 
hopefully be released early next year (but no promises). After that, there 
is no definite feature set or timescale that I know of.

Sorry I can't be of more help.

Cheers, Chris.
