I have been troubleshooting an issue with our backup solution for about 6 months now. The current setup is a system running unRAID and then we have an Ubuntu VM running urBackup. When urBackup goes to purge old files, it locks up the VM and will also lock up the WebUI of unRAID. We can go in and do minor non I/O related things via SSH or directly. urBackup is a great solution but at this point it is just not working for us. I have been on the unRAID forums trying to troubleshoot the issue, because at first I thought it was an issue there. I am here to figure out if there are any suggestions users here can think of? Thank you for any input.
