Scenario: you start a backup to a network storage. The process starts, some data is written to the destination, then backup stops with an error 0x200004 or 0x11025 (“cannot copy / write file” or something similar)
This typically signifies connection problems. It’s an extremely rare issue we haven’t been able to reliably reproduce, and it usually occurs independently of Paragon programs and affects other data transfers. You need to test this by copying a sufficiently big file to the destination folder. The size should be comparable to the archive fragment size (default 4 GB). See if the transfer completes successfully. If the network problem confirms, you need to troubleshoot the network connectivity before backing up. The most basic troubleshooting steps are to check network interface drivers, ping the destination with big packets, and traceroute it to see if there’s some data loss and where it occurs. It’s also advisable to check the physical connection.
