This is regarding the HUB backups. First, see here https://www.screencast.com/t/hzxfbbmt
and here https://www.screencast.com/t/R1f3hsKASZj
and notice this awesome feature that is automatically done . . . here:
This is a host of mine that uses https://www.r1soft.com/
It takes a iniital backup and then only needs to back incremental changes moving forward. This saves massive space and also allows for more checkpoints easily and it also reduces server load.
It is, in a word, fantastic.
Could you all look into this to allow similar or even partner up with https://www.r1soft.com/ to integrate?
Let me know . . . I think it makes such total sense for WPMUDEV backups and your users would LOVE YOU TO PIECES even more than they do not (including me)!!!
