Mac – How to make Time Machine Only Backup Emails

backupemailmail.appms officetime-machine

I know Time Machine is a great backup system on Mac, but I don't like it when it starts backing up everything on a mac.My work is completely done on emails and these emails now need to be backed up as the mailbox is filling up quickly. I am using Apple Mail as well as Outlook 2016 for Mac, both with different email ids. I need to backup both of them so that I don't lose any emails and also if I need to access those emails in future I can do that easily. Here Time machine is a great app to backup but I don't want to backup other stuff, I just need it to backup my email database. Is that possible, if yes then how can I do that and if no then what are other possible options I have as an email backup system?

Best Answer

You can work out with Time Machine to exclude all the other folders except your Apple Mail Database Folder and Your Outlook 2016 mac database folders. As you haven't mentioned which version of Apple Mail you are using so here is how you can find your Mail Database Folder:

Find and Open the Folder Where OS X Mail Stores Mail

To go to the folder that holds your OS X Mail messages:

Open a new window in OS X Finder.

Select Go | Go to Folder… from the menu.

You can also press Command-Shift-G.

Type "~/Library/Mail/V3".

Press Enter.

You can find your folders and messages in sub-folders to the V3 folder:

Local mailboxes are in the Mailboxes sub-folder.

POP email accounts can be found in sub-folders with POP- in their name.

IMAP accounts' mailboxes are in sub-folder that have IMAP- in their name.

The messages are stored in .mbox folders, one per OS X Mail email folder. Open and explore these folders to discover (and open or copy) the emails saved as .emlx files.

Find and Open the Folder Where Mac OS X Mail 5–8 Store Mail

To open the folder where Mac OS X Mail keeps your messages:

Open a Finder window.

Select Go | Go to Folder… from the menu.

Type "~/Library/Mail/V2".

You can have Finder auto-complete the folder names by pressing Tab.

Click OK.

Mac OS X Mail stores the mailboxes in sub-folders to the Mail directory, one sub-folder per account. POP accounts start with POP-, IMAP accounts with IMAP-.

Find and Open the Folder Where Mac OS X Mail 1-4 Store Mail

To locate the folder where Mac OS X Mail 1-4 stores mail:

Open a new Finder window.

Go to your home directory.

You can use the Home toolbar button or

select Go | Home from the menu to go home.

Open the Library/Mail directory.
