Is it possible to make synchronization on demand, with explicit synchronization confirmation on both ends: NextCloud and PC/mobile phone?
Synchronization could be initiated via UI of NextCloud portal or via UI of the PC/mobile app. But that initiated synchronization is to be confirmed via UI on both ends: NextCloud and PC/mobile phone?
I would prefer to synchronize my data say once a week or daily, having changes committed into NextCloud like Source Control systems (like Git or SVN) do.
I would like to control what files exactly are being synchronized.
I have about 50K files to store/sync. Imagine that I get some sophisticated virus on my PC which would slowly but surely be corrupting data in my files. By the moment I figure it out (several days of weeks) this virus may corrupt thousands of my files and they immediately would be syncted to NextCloud and ALL other my devices (as synchronization works now).
Just imagine how much time it would take for me to go through all of the changes history on NextCloud portal and file-by-file manually roll back to closest valid version.
On top of this, imaging that you have a virus corrupting data on one of your devices – and that wrong data would be immediately synced into your ALL devices.
The more devices you have the more chance to get a virus and more chance to get your data corrupted on your ALL devices and more chance to almost lose your data.
Confirmation on both sides would be helpful
a virus on your PC is corrupting data in your files and is silently trying to synchronize the changes into NextCloud; unless you confirm on NextCloud side (over web UI) this synchronization it would not complete.
And vice-versa, a virus could potentially get to your NextCloud – in this case your PC/mobile app will not allow synchronization without your confirmation.
With sync on demand the history would be much shorter and more granular and as a result - more controllable.
