When you’re using Gmail for email communication, the good thing is that it doesn’t require any additional resources (like third-party software) to export or backup your mailbox data. All your messages and items in the Gmail mailbox can be downloaded via POP and IMAP. It’s easy to backup, export, and import your data—all you need is to sign in to your account and create an archive.

MBOX uses a single text file format to store its emails (in concentrated format—each message is saved one after the other). Also, MBOX is a free, open-source format supported by man email clients like Thunderbird, Apple Mail, Eudora, and many others. And Gmail allows users to backup their mailbox data in MBOX format. They can restore this MBOX backup file to Gmail when there is a need.
