backup-rotate

Backups rotations should work within backup spans of 1 hour <= time between backups <= 1 day

How it works

When the script it run it will run the backup command given in backup_command. It will then look in the backup_dir directory for files that end in the extensions in file_exts. If files are found they are renamed to name-<modify time>.<extension> and copied into the relevant archive directories.

Folders

/latest

This contains the very latest backup. 1 file only

/hourly

This directory contains all backups from the last 24 hours. Each file in /latest is copied here. May contain > 24 files if files are backed up more frequently than every hour

/daily

This direcotry contains backups from previous days. When a file is backed up with a modify time on a new day, the previous backed up file is moved here.

/weekly

This directory contains backups from previous weeks. Contains up to weekly_count weeks worth of files. When a file is backed up with a modify time on a new week, the previous backed up daily file is moved here.
