Computer hangs during external drive backup

Hi,

I am using 2 external drives (both 2 TB) and try to backup the first to the second one. Data is about 900GB. First backup succeded after roughly 15 hours. Then I tried 2 times to backup again after adding some extra photos on the drive but at some point my computer becomes unresponsive (I tried giving it time, a lot of hours but no luck). Unfortynately after forcefully rebooting my pc I dont find any log files from duplicati.

Any ideas why might that happen?

Welcome to the forum @ntouev

Windows? Any idea of capacity? Some systems get resource overloaded and unresponsive.

Browsing the web extensively can do that for me, as memory usage tends to grow over time. Certain sites also seem to drive the browser into an extremely rapid memory growth. It’s bad.

Performance tools (if you can get any going at the time) can provide data on what’s going on.
Windows Task Manager is a basic one, and its Performance tab can start Resource Monitor.

Sometimes a disk-active LED or system fan noise level will give a clue, even if GUI is frozen.

Windows Task Manager can sometimes be launched with Ctrl-Alt-Delete even if not normally.

The main job log reports the results from the finished backup, but you rebooted before finish.

The destination drive would have some clues from the file times found there, sorted by date.
System was at least working a bit at the time of the newest file, but that’s a pretty rough test.

An initial backup would probably give a steady flow of files. Update needs to locate changes. Monitoring source scanning (if you wish) could use log-file=<path> log-file-log-level=verbose.

Hi @ts678, thanks for the fast and detailed response.

I managed to make it work. I was using duplicati in Ubuntu but the disks were formated for Windows (NTFS).

Running duplicati on Windows worked the second time as well and was a lot faster. I am not sure if that was a coincidence or not but could make sense I guess.
