I am running an Apple Time Machine backup target on the TN Core host.
The respective datasets for this are set up with a quota limitation. This is seen by the macOS backup clients. I have not yet tried if Apple TM is able to work as intented by deleting older backup versions once the storage is running out.

"Reserved space for this dataset > Default of 0 is unlimited. Specifying a value means to keep at least this much space free and is suitable for datasets containing logs which could otherwise take up all available free space."
Just a confirmation if I understand this correct:
So this refers to the storage space of the pool?
for example:
100 GByte is the amont I want to allocate for 1 macOS client backup storage on TN host.
Currently 50 GByte have been used. The TN Core pool has other datasets, where new data / files are being stored to.
For Apple TM:
I will set "dataset quota" to 100 GByte to limit the max. amount the Apple TM machine backup can have from the pool storage.
I will set "dataset Reserved space for this dataset" also to 100 GByte to ensure that these 100 GByte are always available from the pool storage.

Difference between quota and reserved space
Just a quick question.. In practice, what's the difference between quota and reserved space in datasets? Seems the same to me.
