Windows file system backups use the default Snapshot copy naming convention. The default backup naming convention adds a timestamp to Snapshot copy names that helps you identify when the copies were created.
The Snapshot copy uses the following default naming convention: resourcegroupname_hostname_timestamp
You should name your backup resource groups logically, as in the following example:
dts1_mach1x88_03-12-2015_23.17.26
In this example, the syntax elements have the following meanings:
When creating a backup, you can also add a descriptive tag to help identify the backup. In contrast, if you want to use a customized backup naming convention, you need to rename the backup after the backup operation is complete.
