Syncing to a non-existent target?

[TheAncient]

I have two external USB sticks that I use for backups on alternating months. I.e. data get backed up on stick 1 in Jan and then on stick 2 in Feb then on stick 1 in Mar etc. I have 2 ffs_batch jobs: one for each of those USB sticks. The only difference between those batch jobs is the volume name of the destination drive i.e. the volume name for the USB stick to be used for that backup.
Here is my concern: If only the USB1 stick is plugged in but the USB stick2 is NOT plugged in, FFS will still happily run the batch job for USB2 and vice versa. If one of those USB sticks is NOT plugged in, shouldn't FFS display an error such as "I can't run this batch job because the target was not found"?
(This is not a major problem as the batch job does "nothing". Obviously, it can't sync with a non-existent drive. BUT: FFS DOES update the time stamp of the last sync and that could, potentially, cause problems.)

It probably does throw an error or warning but you likely have it hidden

You are correct: I had "Ignore Errors" checked as quite often I get errors regarding syncing from multiple folders. That brings me to another question: Is there a way to let it display one type of error but suppress another type of error? (yeah, I know: that's asking a lot)

Tools -> Options -> Show hidden dialogues....
You can apply checkmarks depending on what you want to see or not see

Excellent! I just excluded the "Some files will be synchronized as part of multiple folder pairs...." error message and I should be back in business.
Excellent customer support! I wish other companies where this prompt!
Thanks Xenon!
