NAME

Dev::Util::Backup - Simple backup functions for files and dirs

VERSION

Version v2.19.11

SYNOPSIS

The backup function will make a copy of a file or dir with the date of the file appended. It returns the name of the new file. Directories are backed up by tar and gz.

use Dev::Util::Backup qw(backup);

my $backup_file = backup('myfile');
say $backup_file;

my $backup_dir = backup('mydir/');
say $backup_dir;

Will produce:

myfile_20251025
mydir_20251025.tar.gz

If the file has changed, calling backup('myfile') again will create myfile_20251025_1. Each time backup is called the appended counter will increase by 1 if myfile has changed since the last time it was called.

If the file has not changed, no new backup will be created.

Examples

The bu program in the examples dir will take a list of files and dirs as args and make backups of them using backup.

EXPORT

backup

SUBROUTINES

backup(FILE|DIR)

Return the name of the backup file.

my $backup_file = backup('myfile');
my $backup_dir = backup('mydir/');
