Created page with "How to backup and restore your system. In this document, we will focus on the system backup and restore it back, including the user applications. == Backup user data == All..."

New page

How to backup and restore your system. In this document, we will focus on the system backup and restore it back, including the user applications.

== Backup user data ==
All user data and changes are stored in '''/mnt/userfs'''. This partition can be backed up by running the command:

{{NotePre
|text=root@buildroot:~# metel-backup
}}

This will create 2 files.

{{NotePre
|text=/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 temporary. After reboot, the content is empty. If you want to keep the backup, move the files to a permanent storage.

== Restore user data ==
Data to restore must be placed in '''root temporary directory(/tmp)'''. Copy the backup files to that location.

{{NotePre
|text=/tmp/backup.tar
/tmp/permissions
}}

Then it is possible to start a data restoration command:
{{NotePre
|text=root@buildroot:~#metel-restore
}}

Before restoring, you will be asked if you want to delete the current user data first.
{{NotePre
|text=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

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.<br/>
Select '''No''' if you want to merge the current user data with the data from the backup. If there is a conflict between files, the backup file is applied.<br/>
It is strongly recommended to do a reboot.

{{NotePre
|text=root@buildroot:~# reboot
}}

== Restore customer application ==
The user application is running on the device immediately when you begin. If you perform an unwanted change and the need to return to the state after purchase, use this option.

Contact:
[mailto:info@example.org support@metel.eu]

In '''/home/''' there are two files with backup of the customer application:

{{NotePre
|text=/home/backup_customer_app.tar
/home/permissions_customer_app
}}

Copy and rename these files:

{{NotePre
|text=root@buildroot:~# cp /home/backup_customer_app.tar /tmp/backup.tar
root@buildroot:~# cp /home/permissions_customer_app/tmp/ permissions
}}

Then run:
{{NotePre
|text=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.
{{NotePre
|text=root@buildroot:~# reboot
}}
