Can you specify the version of the product you're using? And also let us know if this is using the new backup format or the legacy format. This is a file backup? You say you're backing up locally, but are you backing up locally to a dedicated drive but can you specify if this is a direct attached storage drive or is it a USB drive, and if USB are you connected through USB 3.0? Also can you check the logging in options to ensure it's not on high. If it is move it to the lower default option and try the backup again. Another thing you can check is the multi-threading settings in options. You want to make sure you're not overloading your CPU during the compression and encryption phase. Either way back up that small should have been pretty quickly. If we can't figure it out here I'll have you open up a support case so the team can review your logs.

Thanks for the reply.

I just installed CloudBerry a few days ago; it's on a Linux machine. It seems to be version 3.2.0.114.

The drive is USB-connected through a 3.0 cable. The line in /var/log/messages reads "kernel: usb 1-1.2.4: new high-speed USB device number 98 using ehci-pci" but I don't know if that means usb 3.0

Settings>Advanced reads Mode: Low
Settings>Network has local storage max speed unchecked

The backup was done with a thread count of 5, chunk size 10Mb, memory used 100Mb

I'm not using compression or encryption

how do you have the external USB drive formatted? What file system? If it's ExFAT that's probably the issue.

No, it's Linux Ext4.

I think you'll need to open a support case in order to get this resolved. It may be related to the errors you're seeing in the log. Please use the diagnostic option in the client to submit the logs to support and mention that I asked you to open a support case in case you don't have maintenance.

Will do, thanks.
