Disk space used falls odwn for 1 day: Is that normal?

Hi,

Disk space used for one of my Storage node (hosting ~2.5-3TB of data) fell down from 75 TBh to 750GBh.

Is that normal?
If I well understand this diagram, it means that a lot of data have been erased on my node and then a lot of new data has been uploaded to it the next day.

Should I be worried about my node health?

Thanks for your help
