After kicking Gmail out, there are still some problems with mailing transfer. I managed to get a full backup using this old but quite efficient tool: Gmail Backup. I think I’ll be using Thunderbird for desktop use.
Next big thing to deal with, is moving my GDrive data somewhere else, outside my computer and it must not be DropBox. I’m not sure yet it is the best one, but I like the way Kim Dotcom deals with his problems. So, I decided to stick to megaupload v2: Mega.
Cloudwards suggests sync.com as the best alternative to DropBox even if Mega offers 50GB (vs 5GB to sync.com) of forver free storage. This is what I need for the moment. Moreover, Mega has a valuable tool called MEGAsync. So, all I had to do is download my drive to a single directory using the desktop Google drive app, and then point it a s a source of Sync to MEGASync… then I just kept my computer connected for one night :).
