In this document, we will focus on the system backup and restoration of the system, including user applications.
Backup User Data
All user data and changes are stored in /mnt/userfs. This partition can be backed up by using the following the command:
root@buildroot:~# metel-backup
This will create 2 files.
/tmp/backup.tar * it contains an image of /mnt/userfs partition /tmp/permissions * it contains file access rights and ownership
Note: The /tmp/ folder is a temporary. After reboot, the content will be empty. If you require a backup, move the files to a permanent storage or some other destination than /tmp/.
Restore User Data
Data to restore must be placed in the root temporary directory(/tmp). It is important to copy the backup files to that location.
/tmp/backup.tar /tmp/permissions
Now it is possible to start the data restoration command:
root@buildroot:~#metel-restore
Before restoring, you will be asked if you want to delete the current user data first.
root@buildroot:~# ls /tmp -rw-r--r-- 1 root root 8824832 Jan 5 15:40 backup.tar drwxr-xr-x 3 root root 60 Jan 5 12:19 cron -rw-r--r-- 1 root root 0 Jan 5 12:19 dnsmasq.leases -rw-r--r-- 1 root root 88731 Jan 5 17:03 messages -rw-r--r-- 1 root root 5129 Jan 5 15:40 permissions -rw-r--r-- 1 root root 55 Jan 5 17:15 resolv.conf -rw-r--r-- 1 root root 27000832 Jan 5 10:06 rootfs.ubi drwxr-xr-x 5 root root 100 Jan 5 12:19 SMS -rw-r----- 1 root root 440 Jan 5 12:20 smsd.log -rw------- 1 root root 0 Jan 5 12:19 sshd -rw-r--r-- 1 root root 4060544 Dec 20 09:32 zImage Do you want to delete all user data before recovering from backup? [y/N]:
Select Yes if you want to go back to a given state of the system.
Select No if you want to merge the current user data with the data from the backup files. If there is a conflict between files, the backup file will be applied.
It is strongly recommended to do a reboot.
root@buildroot:~# reboot
Restore User Data to Factory
The user application begins to run on the device immediately once you begin. If you perform an unwanted change and need to return to the state after purchase, use this option.
Contact:
support@metel.eu
In /home/backup there are two files with backup of customer applications :
/home/backup/backup.tar /home/backup/permissions
Copy these files to tmp/:
root@buildroot:~# cp /home/backup/backup.tar /tmp/backup.tar root@buildroot:~# cp /home/backup/permissions /tmp/permissions
Then run:
root@buildroot:~# metel-restore Do you want to delete all user data before recovering from backup? [y/N]: y
It is strongly recommended to do a reboot.
root@buildroot:~# reboot
