Questions
- What operating system is your computer using?
- What antivirus program are you using?
- What is the key bottleneck? Is it using a lot of CPU, a lot of I/O, etc?
If using Windows, please open the resource manager during a prune and check what process(s) are accessing the disk. As I discovered in this thread antivirus programs can massively increase the time required to do backups / prunes. I found I had to give restic an exception to virus scanning. In the end I got rid of Avira and used Windows Defender, I can’t remember if I had to create an exception for that or not.
