In which @Captain Transfers a 500GB File

@flabdablet said in In which @Captain Transfers a 500GB File:
@Captain Can you not just copy the 500GB file off one of the backups, then?
Yes this
-
The problem is... virtualization and bad random read performance. A virtual machine is running on the same drive as I'm doing a transfer from. The random-read nature of the task just murders the IO rate. In fact, there's random reading at two levels... switching between the VM's virtual disk and the file I'm copying, and the switching that occurs within the VM's virtual disk.

@Captain how's it even making backups, if copying a 500 GB file causes it to fall over?
-
@anotherusername They're made incrementally, at night. It's not that the whole server falls over -- it's that the file-server virtual machine (which is also running a few other services) starts to run too stupid slow to do its job while any big transfers are going on. It goes from being able to handle 50+ users to maybe handling 10.

Well, you should have enough suggestions by now.

@ChrisH Yup, thanks everybody.
