Offsite Backup to Synology NAS keeps failing
We have a Hyper-V server (192.168.0.19) with 2 virtual machines that need to be backed up. (60gb and 260gb). separate physical machine running Veeam 12.3 to back them up (192.168.0.5) It backs up to the onsite nas just fine. The offsite nas though is another story.
Recently I moved it to a different offsite location than it was before and replaced the laptop that was acting as the proxy server so now it's synology nas (192.168.4.25) and proxy laptop (windows 11)(192.168.4.15). Main office has a fortigate router and the secondary office has a unifi router if it matters, both with addresses of 192.168.x.1
main office has gigabit internet and secondary office has 50mb/50mb internet however when I run a backup job it won't go above 10 and in fact is usually 5 or lower. The jobs will run for a long time because of this and sometimes the 60gb one will finish but never the 260gb one. errors will either be:
"Failed to pre-process the job Error: The process cannot access the file because it is being used by another process."
or
"Error: An unexpected network error occurred.
Asynchronous request operation has failed. [requestsize = 614400] [offset = 4450836480]"
The jobs default to 192.168.0.19 for proxy server and I can't find the setting to change it.
I've been googling and trying different settings and can't quite seem to find the right combination and now I'm gonna put my hand up and ask for help.
don't be afraid to start with the basics because I could have easily missed something.
