Create a backup copy of the file with Perl
The FileBackupCopy module provides functions for creating backup copies of files. Two backup schemes are supported simple and numbered backups. In simple or single backup scheme, only one backup copy is maintained for the given file. Its name is created by appending a single tilde character to the original file name. In numbered backup scheme, arbitrary number of backup copies can be created. The name of each backup copy is created by suffixing the original file name with ‘.~N~’, where N is a decimal number starting with
- Additionally, the automatic backup name scheme is implemented. In this naming scheme, numbered backups are created if at least one numbered backup copy already exists and simple backups are created otherwise.
