Following enviroment variations exist for raspiBackup in next release 0.6.2 which supports Raspi3. For all new features available in this beta see this page. Resource constraints limited the number of variations tested. Please add a comment when you successfully tested a variation which is not marked as tested. If you don't know for sure whether your scenario was already covered in the table don't hesitate to ask. We'll figure this out.

How do you have to read the tables?

The dimension table depicts the parameters which influence the backup and restore process. For backup it's for example

1) Raspi version: Raspberry version less than or equal 3

2) Boot device: Whether the Raspberry is booted from SD card or in USB boot mode from USB stick or disk

3) Backup type: raspiBackup type (Option -t) - dd, tar or rsync

4) Backup mode: raspiBackup de normal or partition oriented (Option -P)

5) External root partition: raspiBackup saves an external root partition if booted from SD card


The test backup matrix is a subset of the theoretically possible 32 variations of all test variation dimensions.

Test# 1b reads as follows:

1) Raspberry version which was used to create the backup was < 3.

2) Boot device was SD

3) tar backup was created

4) backup mode was normal

5) no external root partition, i.e. the root partition also resides on SD card.


The test restore matrix is a subset of the theoretically possible 64 variations of all test variation dimensions and reads in a similar way.
