[Box Backup] lazy and snapshot together, file formats and files changing often

Chris, thank you for asking our opinions.

I wold say that a "snapshot" is typically understood to be a full, current 
image of the backup schema. In that case, I would think that a "snapshot" 
would be a full backup of all files at the time of the bakcup, and a "lazy 
mode" backup would be using the current setup of only backup up changes as 
noted in the original e-mail below. It would be nice to have a system set 
to "lazy mode" and be able to run a manual, or schedule for periodic 
occurrance, full "snapshot" backup.

While I'll find this software useful, what I'll be waiting for is having the 
ability to make backups where I or the end user could choose to backup a 
different snapshot, if available, to help protect against corrupted data in 
the latest lazy mode backup.

I'm thinking that this could either be done through a full snapshot as noted 
above, or having the system be able to differentiate between different lazy 
mode backups, basically picking which "change" level to restore from. I hope 
that makes sense, and I do understand that having either of these options 
enabled would take more storage space.

Just my vote/opinion.
