EMail Backup: lm-backup.tar.gz: No such file or directory

[Alberto.ricof]

Hi Habib,

The new FW 1.2 for SL and 1.5 for HL requires a change in the mail script.

1) Make sure you have changed your g-mail account to enable HL to send e-mail on https://www.google.com/settings/security/lesssecureapps
2) Change user and password in the script
3) Change sender and receiver details in the script

Code:

Hi Erwin, 

I am trying to send backup by email with the scritp you mention, but google throws me an error (I send the capture). My HL is in the latest version, both soft and hard.
Maybe the solution is to change the mail provider? Any suggestions in the scritp to keep it?

Thank you very much in advance, I learn a lot here :-)

Regards,
