I have several devices linked to my Google Drive account, when I delete a file it’s stored on all those devices AND google drive, and when I empty the trash from Google Drive, it (apparently) takes insync a month before it deletes it from all those devices, unless I then go and delete it manually again on a device.
I have a small raspberry pi single-board computer, with limited storage, I am having real problems managing this storage with insync enabled on that device. It’s got 15 gigs of storage, but a fair chunk of that is .insync-trash. To clean this out I have to go to Google Drive and empty trash, then return to the device and empty .insync-trash. This results in me losing all my “undelete” capability from Google Drive because in order to do basic maintenance on a single device I have to regularly empty my trash on Google Drive. This is not helping!
Basically, please let us completely disable the retaining of deleted files, they are stored on Google’s servers and on other machines using insync, so at least let us completely turn it off on devices when we want to, it’s a real major pain in the neck to deal with. In order to cope with this I am having to compromise my ability to recover deleted files because of insync needing my google drive trash to be emptied routinely, so please please please finally add this option, let us disable .insync-trash completely!
