#Backup Script

A simple backup script utilising OpenSSL, tar and rsync, written in bash.

##Script Features

• Incremental backup retention
• Backups are encrypted with AES256-cbc with SHA1 message-digest
• The backup script can store a copy both locally and on a remote device/server
• Backups are sent over SSH
• Currently supports GNU/Linux and FreeBSD

##Backup Retention

By default:

• Daily backups are retained for the past week
• Weekly backups from Mondays are retained for the past month
• Monthly backups from the first Monday of each month are retained for the past six months

The retention lengths are adjustable in backup.cfg:

If desired, the backup deletion can be run seperately:

• To delete local backups, run "deleteoldbackups.sh"
• To delete remote backups, run "deleteoldbackups.sh --remote"

##Arguments backup.sh:

• --config [filename] : Specify a different configuration file (or location)

deleteoldbackups.sh:

• --config [filename] : Specify a different configuration file (or location)
• --remote : Delete remote backups (local backups are deleted by default)

Note that deleteoldbackups.sh is run both locally and remotely by backup.sh by default.
