How to Backup and Restore
SD card on Raspberry Pi could get corrupted as majority of users do not use graceful shutdown. Also power interrupts could cause same issue. So it is good to have backup around.
One of the options is to take full image from SD card, but it is both time consuming and inefficient. But there wide range backup solutions could take SD card image and restore.
Which files and directories are important to take backup?
There are three types of files you may need to take backup.
- NanoDLP settings
- NanoDLP plates
- OS configurations
NanoDLP settings and plates
There are two ways to do it automatic and manual.
Automatic backup / restore
Backup / Restore functions available on the tools page.
Manual backup / restore
There are two folders which you need to take a backup.
To restore just terminate NanoDLP.
sudo service nanodlp stop
Then replace both folders and start nanodlp
sudo service nanodlp start
Only way to do it without doing it manually is to use debug export from tools menu. Restoring is fully manual. A debug file contains both OS and NanoDLP settings (without sensitive information such as wifi password and etc)
Important files such as config.txt may contains many important settings such as display configurations and hardware parameters.
