Hello @RomanZ, first of all I want to thank you for your advises. I choose another folder in my Linux box for second device , but the name of the folder from remote device (android #1 and android #2) are the same - "DCIM" and there is no option to change that - from device or when I try to add link from second device. That is the problem. And one more problem - i realize that when I erase some picture from my device it is erased in folder in my LInux box. I clearly understand that this is SYNC program, but maybe will be better photos from the devices to be marked or something else like "special" folder and not to replicate deletes on the backup storage.
