Data loss is a subject frequently seen posted here in the Community and is one of the more difficult issues to address.
I wanted to share a story of a user who posted on DSLR of data loss issues but had the stamina to "keep digging" and found the overlooked source:
"Data Disappearing w/ non-usage. So what IS the ANSWER?The ol' disappearing data is finally happening to me I've read tons of complaints and hoops HughesNet makes you jump thru and questions to answer. But what I haven't read is what the cause has been determined to be and more importantly the ANSWER to how to stop it. To those that answer no to all the questions about usage and connections, etc and nothing applies to you, has there ever been a resolution? If so, what was it? I've yet to find an answer which makes me think it's them, not us! I'm on Gen 4"
The user replied much later:
"I posted this on another thread concerning the same topic but wanted to post it here too. I'm sure there are others with the same problem...
OK, I have solved (my) disappearing data dilemma. I hope it helps someone else. I found the answer a couple of months ago and things have been back to normal ever since I unplugged my Google ChromeCast dongles (2 of them).
Yes, Chromecast downloads those beautiful backdrops to the tune of 8-10MB an hour. I have two of them so it was totaling 15 to 17MB/hr. If you add that up it's over 10GB/month but you have to consider the bonus time where the data used is not going against you. Since I've unplugged the ChromeCast dongles, data usage has been normal.
Most people won't notice the data usage but satellite people sure will! As of right now, I know of no way to stop Google from downloading this unwanted data. Too bad because I really enjoyed my ChromeCast."
Tracking data loss issues requires a structured approach and plenty of patience.
Take nothing for granted, suspect everything until it is proven not to be the culprit.
In many cases critical settings are reset to default values by updates. In other cases (my Garmin GPS updater) software just doesn't do as its told.
I usually leave my Samsung Galaxy tab4 at work. Due to some connectivity issues I brought it home for a week. It chewed through 879 MB despite me having "pruned" its settings.
When it went back to work the "excess usage" stopped.
Those wireless devices are pesky.
