Problem backfilling with promtool

Hi all!
I’m very new to Prometheus so i’m sure i’m doing some simple misstake here… =) I want to backfill with some historical using promtool. So i have a text file in the below format.
About 150k lines, data ranging from late 2019 to today.

TYPE volume_space_physical_used gauge

volume_space_physical_used{aggr=“aggr1”,cluster=“mycluster”,instance=“localhost”,datacenter=“mydatacenter”,job=“manual”,node=“mynode”,style=“flexvol”,svm=“mysvm”,volume=“myvolume”} 28271448064 1569710476.0

EOF

I am testing on Windows, so i start it up using:

prometheus.exe --storage.tsdb.retention.time=4y

Next i run the promtool to import the data:

c:\promtool tsdb create-blocks-from openmetrics c:\new2.txt
BLOCK ULID MIN TIME MAX TIME DURATION NUM SAMPLES NUM CHUNKS NUM SERIES SIZE
01GF0SJFQDB1X5F53NN0XTVKPZ 1569710476000 1569711505001 17m9.001s 22 22 22 5126
01GF0SJG0QSNVBF8T9QKDADW7X 1570313870000 1570317696001 1h3m46.001s 22 22 22 5126
01GF0SJGAKMEYSKZCJ4YMH1PSG 1570920905000 1570921072001 2m47.001s 39 39 39 7957

And so on. Looks good, import seems to be working.
I then restart prometheus to check how it behaves:

and so on for a lot of blocks. Looks good, seems like it finds some stuff to work with.

Problem 1: Looks like Promethues starts deleting stuff, despite the 4y retention:

ts=2022-10-10T11:25:49.627Z caller=compact.go:460 level=info component=tsdb msg=“compact blocks” count=2 mint=1573947514000 maxt=1573949437001 ulid=01GF0T9P2AHFY6H0Z086TSV8NE sources=“[01GF0SP74KAA9H7J6064S29XSZ 01GF0SP7P0S9QEH83V13QE9412]” duration=113.2907ms

And so on for a bit. It doesn’t delete everything though as i can still see blocks in the ‘data’ folder.

Problem 2: I get no matches when searching, but i can see that the metric is there if i go to the metrics explorer. What i am doing wrong?
Do i need a .yml file with some parameters that match what i am loading or something?

Cheers!
