Handle With Linux

Windows has VSS, this blog is questioning why there isn't something similar in Linux
from the blog:
"But where’s Linux?
Linux distributions don’t have any equivalent feature.

The result has been a few one-off solutions focused on a particular application stack, but for the most part applications just suffer from inconsistent snapshots on Linux. "
