Unable to create full snapshot

I’m running Hassio v191 in a Docker container on my Synology DS218+ NAS. I have made a clean installation of Hassio which is running fine but if I attempt to create a snapshot it stops after a few seconds and reports that the snapshot has been completed even though the resulting filesize is only 4-5MB. The logfile does not indicate any problems. Can anyone help?
Thanks

Early snapshots are very small since not much has been recorded to the database. 5 MB is not out of the realm of possibility.

5 kB and maybe we have a problem :wink:

I have several addons enabled (Aircast Airsonos, Dasshio, DuckDNS, Hass.io Google Drive Backup, Log Viewer, Motion Eye) and was puzzled because the snapshot files for my previous installation were nearly 200MB in size. Thanks for your advice, will see if they get bigger as time goes on.

You can open the files and check the contents.

Yep, it all seems to be there! Thanks again.
