Pause Cache command for Backup?
Posted: Sat Oct 29, 2016 4:45 pm
Do we have access to any sort of "pause cache" command (like a toggle on/off) so that we can disable during a system backup/drive imaging?
The reason I ask is that I've been doing a monthly drive image to a NAS, and then daily incrementals off of that. And my cache hit rate has gone to crap (<20%) as a result. And I completely understand why, it's just not advantageous at all when doing regular backups of a system. I'd like to be able to temporarily (and automatically) flush the write buffer(s), pause all caching, and then restart caching when the backup is complete. Either a powershell script command, a VBS command, or even a command line toggle would work. I just haven't seen anything like this available, or missed it somehow.
