Yes, plz.   need a way to back up my Thunderbird .   I keep ALL emails from the past and consider this historical record so important, that I'm ready to devote as many gigabytes as necessary to maintain this.

Does MOZBACKUP still work??

Familiar face
  1. Upgrade to Thunderbird 102 and use Export of the tools menu.
  2. Use the Scheduled Backup in the import export tools addon. ImportExportTools NG :: Add-ons for Thunderbird It is slow,  but only kicks in when you shut down Thunderbird.
  3. Or just use a third party backup solution to back up your files when Thunderbird is closed, along with your documents and pictures.  I used the one in Windows 7 for years.  Microsoft saw fit to remove it from Windows 10.  But there are many competent backup programs available.  Some free others not.

When backing up Thunderbird profiles,  if all the default locations for storage are left alone.  All data needed to be backed up to restored "as is" will be found in the windows directory %appdata%\Thunderbird or subdirectories of that.  So simply copying that folder and it's sub folders to another drive will create a backup.  %appdata% is a windows placeholder that the file explorer will resolve to the users hidden appdata\roaming folder.

I do not recommend anyone use mozbackup as it has remained without any sort of update in the last decade.  Given it was written in Borland Pascale,  even though they made the source available for others to update,  it is very unlikely anyone will take them up on the offer. The language was always rather niche.

It is suggested to add the Scheduled Backup feature for Thunderbird.

Senior here...NOT fully educated in computer use...but using one for over 25 years.  I am NOT enthused with the NEW version of Thunderbird.  If I canNOT EASILY get back the version BEFORE this horrible update...I will be using something else.  FED UP, with constant changes.  WE LIKE the OLDER  version.

Give us a CHOICE when you make updates to install or NOT.  I thought you liked the public???

Disgusted again.
