text: I have a bit of an issue, I am running HA on a RPI 4b with a 32Gb MicroSD card. The storage is approaching 100%, currently 97.2%:
  I have 2 issues.
  I don’t know what is taking up so much space, how can i find out?
  The System information says: “Estimated database size (MiB) 436.76 MiB”
  I have Influx DB set-up for longer term data storage, could this be taking up so much space?
  With so little space available at the moment, I can’t install a Terminal Add-on to investigate further, how can I clear some space or move data to an external disk temporarily?
  Ok so I had a look, the recorder is definitely only recording 7 days worth of data. There are no back-ups on the SD card, I have 2 back-ups on a NAS and when I made that change I deleted the old back-ups on the SD card, could they have lingered? Is there a way to find out?
  Influx is only reporting to be about 500MB worth of data which feels about right.
  I have just done another back-up onto the NAS, the back-up size is 900Mb, ~700 of which is the influxdb.tar.gz, which again is close enough with what Influx reports to be the size of the DB, assuming that includes the influx configs and add-on files. The homeassistant.tar.gz is 200Mb.
  Thoughts? Could I just wipe the SD card completely and install HA fresh and then restore this new back-up?
  Is there another way of finding what is filling up the storage?
