Simple scripts to backup OpenWRT to USB device.
Script assumes that USB device is /dev/sda1, and mount point is /mnt/usb. Can be easily changed by modyfying variables in the begining of files.
Just run command and backup will be created. Older backups will be removed - time of oldest you can modify in variable.
Example crontab:
4 2 * * * /bin/sh /root/backup.sh
5 2 * * 1 /bin/sh /root/backup_mtd.sh
