So the full partition could have been the cause of other errors, like:
sssd[krb5_child[6702]]: Credentials cache I/O operation failed
Remember to check the log for this error on the next backup. If it doesn’t occur anymore then it was probably caused by the space issue:
The next one is related to samba shares:

The following could be due to failed service or duplicate port:

Another one refers to a firmware bug (you can search for firmware updates for your hardware, if any), and could be related to time skew issues.
kernel: [Firmware Bug]: TSC doesn’t count with P0 frequency!
More info:
The AMD processor has the x86 constant TSC feature enabled but the firmware has not set bit 24 of the MSR MSR_K7_HWCR and so the processor TSC does not count in the P0 frequency level.
Some errors/warnings might be harmless and could be ignored, but I don’t know which ones.
