How unix backup works?


Can anybody please explain how unix file system backup works ?
We have vss in windows filesystem backup which is needed as there are many files being used at the time of backup, what is the similar technology in unix?

And for a unix incrimental backup, is netbackup using atime or mtime to backup changed files?

The architecture on Unix/Linux is different from Windows - there are no concept of locked file in Unix/Linux

Files in on *nix system may be busy - open by a application, but it can still be read if permission allow.
