RSYNC 2 of 3 partitions shows error

[Tytouc]

Hi,
I have a Raspi w/ Buster and I'm using RSYNC method for a backup.
My PI boots on an external SSD where I have 3 partitions:
1: boot
2: root mounted as /
3: data mounted as media/USBDisk

I only want to backup partitions 1 and 2, hence I use RSYNC with "Backup mode= two standard partitions"

But, executing the following command "sudo raspiBackup -m detailed" I get an error stating the following:
??? RBK0013E: More than two partitions detected which can be saved only with backuptype DD or DDZ, with option -P or with option --ignoreAdditionalPartitions.

I thought, that configuring the 'two standard partitions' was ok w/ RSYNC to backup only boot and root partitions.

If I select "Backup mode: more than two partitions" and -elect only boot and root partitions (1 & 2), than I do not get this error.

here is the complete list of parameters:

Backup path: /mnt/xxxbackup/
Backup Version: Smart backup strategy : 0 4 12 1
Backup Type: RYNC
Backup mode: Two stad Partitions (boot & root)
Message verbosity: Display important messages only
eMAil sent to: myemailaddress@myemailserver.com / msmtp
Regular backup: Enabled : Each Sunday at 05:00

Anything I'm doing wrong?

Thanks for your help

I see your point.

RBK0013E was introduced because I got complaints from raspiBackup users: They expected raspiBackup to backup the whole system with all partitions but only the first two were saved. Keep in mind raspiBackup exists already a long time and initially there was no installer which makes clear only the first two partitions are saved.

You found an alternative and decided to use the partition oriented mode and save only the first two partitions. I suggest to use either the invocation option --ignoreAdditionalPartitions or just change DEFAULT_IGNORE_ADDITIONAL_PARTITIONS=0 in the config file into DEFAULT_IGNORE_ADDITIONAL_PARTITIONS=1.
