Hey

I've setup two VM Guests on Hyper V 2008 R2 Server.  All good except I'm having to backup to 1 TB USB Drives. Basically the whole system backup selection is about 900GB. It's getting close to what the 1 TB drives can hold. I have found that it is expected behaviour for Hyper V to create the .bin file equal to the amount of RAM on the VM guests. In my case this equals around 50 GB. Can I exclude these .bin files from my backup?

There are no snap shots of these machines, the .bin are purely related to the running machine. If I shut the machines down the .bins dissapear. I'm just looking at NOT" backing up 50 GB of unrequired data.

Thanks

How to exclude those .bin files depends on your backup software. What are you using?

backupassist (image job). It's not so much how but can they safely be exlcuded. Backup assist will allow me to exclude paths/files but I would like to know if this is recommended.

Thanks

The .bin file is a copy of the VM's RAM, and can be safely excluded.

Thank you. Do you happen to have a reference indicating that this file is not required to sucessfully restore a VM

Personally, I only backup the VHD files. If I need to restore the VM I detach the existing VHD, overwrite it, and then reattach the VHD. You can also just attach the VHD to a new VM and boot it. I have done this many times. I never take Hyper-V snapshots...they can lead to lots of issues.

BIN files are a critical part of the system - they provide integrity and failsave for the VMs.
 
The size of the BIN matches the amount of RAM you have given the VM.  Give the VM less RAM and you have a smaller BIN.
 
BIN files need to be ignored by both backup and AV utilities.
