Future Request: If either source OR target are not available don't sync

Posts: 3 · nickreserved 2 Jan 2015, 15:21

I have a small LAN and I backup all PCs and some usb disks to one PC.
I have many source-target pairs in my file.
When I decide to sync, there is no guarantee that all PCs are on and all usb disks are mounted.
So, FFS marks for deletion all of coresponding target files.

SO:
If source directory is not available, skip sync. Don't delete target files.
If target directory is not available, skip sync. Don't delete source files.

This functionality is already implemented. Is there a problem with it?

I believe the same, but seems to be a problem.
I attach 2 screenshots of my 6.2 version (6.12 does the same thing).

This problem is caught at a later stage: if you try to start sync you'll get the error "source folder not found".

@Zenju:
Suppose the resource that was off-line during Compare
does become on-line between the Compare and Sync action,
would that now pose a risk of loss of data in FFS?

No, because FreeFileSync checks folder existence only once: no matter if the device becomes visible later or not, starting sync will show a fatal error and skip the corresponding folder pair.
