Description
We have 2 databases on same host. From time to time we notice that huge chunk of data is missing across all measurements. I'ts like someone hit delete from where time > X and time < Y.
First two times we tried to re-create the data in influx manually because it was in smaller DB ("only" few thousand records were missing). By accident i figured that if we backup our database and just restore it back, all the data is back. So data is not lost, but influx is not showing them. Few days ago we had identical situation with our larger database. Everything from July 12, 2018 to August 23, 2018 - gone!
We did backup/restore (12 GB dump), everything is back! Any ideas?
We use default RP, so none/infinite, no CQ, version is 1.5.2. It happened before with 1.2.4 also.

Research direction
Start by reviewing the reported gaps across measurements, including the July 12–August 23, 2018 interval, the default retention policy, and the backup/restore behavior. Compare the InfluxDB 1.5.2 and 1.2.4 reports on Debian 8; done means identifying why data is hidden and documenting a reproducible cause or fix.
