Vu Ultimo - BH 2081 - Backups Questions

Hi,

I wonder if you can please help clarify regarding questions on Backups for Vu Ultimo running BH 2081 which has all the personal plugins installed and configured as desired:-

- How I can a take a full image snapshot of the receiver configuration and restore it from the internal hard disk or USB stick?

- On the BH 2081 Backup menu, what are the differences between the Full Backup and Personal Baclup menu options and what filenames are created and their location on the hard disk when used?

- In the receiver's hard disk directory path media/hdd/backup what is the purpose of the file which exists enigma2settingsbackup.tar.gz and 2014-01-21-enigma2settingsbackup.tar.gz and how are they created?

- In the receiver's hard disk directory path media/hdd/fullbackup_ultimo what is the purpose of the file which exists 20130917_1744 with a subdirectoriy called vuplus and another one below it called ulltimo (containing file root_cfe_auto.jffs2 and kernel_cfe_auto.bin)?

- Under the Software Management section, what are the Backup System Settings and Restore System Settings features?

- In the directory media/hdd what is the purpose of BhPersonalBackup.bh5 file?

- Under the Software Management section, Advanced Options, Advanced Restore a list of files such as
2014-01-21-enigma2settingsbackup.tar.gz is shown and where does this fit in the scheme of things?

Many thanks in advance for all your support.

With kind regards.
