Online mail users without a software client should still make sure that their precious emails are backed up regularly to avoid data loss. Now Gmail Backup can be used by Gmail users to perform regular backups of all stored Gmail messages.
Gmail Backup will backup all Gmail mail folders and mails contained within including labels, dates and from fields. Before the backup can be started users have to enable IMAP in the Gmail settings. Once that nuisances is out of the way it is possible to backup all Gmail messages with minimal interaction. If desired a time interval can be set to restore only emails of a certain period and not all of them.
Interestingly enough emails will be stored in Microsoft’s eml format which makes it easy to import the messages into other mail clients. Gmail Backup provides an restore option to restore previously backed up emails; Not necessarily though to the same user account since the name and password of the user account can be specified freely whenever Gmail Backup is being used.
An alternative to using Gmail Backup would be to configure a regular email software client like Mozilla Thunderbird or Microsoft Outlook to retrieve messages from Gmail. There would not be an obvious restore option though for those messages.
