Virtual Server Backup

@Rafael Santos It certainly is possible to use both the VSA and the File System Agent on the same client/server. In most cases, it would be redundant though as you are backing up a lot of the same data. From my experience, for a larger server (some say rule of thumb is > 1 TB, others 500 GB, depends on various factors), is to use the File System Agent as a Browse for a Restore will tend to be faster. For a smaller VM (less than 1 TB, 500 GB, again it depends), it is best to use the VSA and you can restore individual files and folders relatively quickly browsing the VM. 

There are various factors at play here, so it is best to do some testing within your environment as well - ie test throughput and browse times using the File System and Virtual agent on the same server. Another consideration is licensing cost, as that differs as well.

@Rafael Santos I will suggest to use virtual server agent backup for any VMs that you are trying to protect.

for any reason if you are having issues or non supported configuration like independent disk then only those servers you can backup using file system agent.

Thanks guys, for the answers.

If it helps, there is a really good video here that explains some of the caveats and best practices with file restores.
