I have large Macrium Reflect disk images.

If I have to interrupt a mirroring job which is just mirroring such a large file, like e.g. a golden disk image, then it has to be started at the beginning in the next run. This is much waste of time.

Would there be a possibility to recognize, that the mirror job was stopped at a certain point and to append to the partial/existing file? Any idea how something like this could be achieved?

Thanks, but not speaking of pausing.

"Interrupting" is the same as pausing, no?
Regardless, the answer is no. FFS can't be stopped mid-file and then resume there later. You can use a utility such as 7zip to split the large file into chunks, which can then be synced in chunks

No interrupting (to me) infers a hard break (aka, Cancel [in FFS]).

And I take it (& kind of expect) that FFS, on Cancel, actually quits any copy in progress, rolling back any file(s) that had not fully completed their copy at the point of the Cancel.

(And with that those file(s) would not have their interim contents left on the target end. [Such that they could be "resumed".])
