@ottawa_admin on many linux distros resolv.conf tends to have a blurb similar to this "# This file is managed by man:systemd-resolved(8). Do not edit." I can't remember how the ES works but that's something that will burn you if it's not configured correctly.
Restarting the mango service itself would not affect it since this is a system level function. What you'd need to do is restart the whole ES so that Linux reboots and then have a look to see if your entries are still there.

Hi @Envari

Have you tried clearing your cache?
Seems like mango is booting up with out any issue.

Just wondering how I should go about doing a backup through the command line in case my backup is a different version than the current interface. I've tried following a previous forum post but I'm not quite understanding the command line sequence.

The post you linked to is about doing a restore on the command line. That command should be able to be run from your Mango directory, but you may need to change the path to the H2 JAR and the mah2 file, due to version numbers having changed. Do you have a more specific question?

All of my data sources are there, however none of my points have their previous values.

You can use the /ui/administration/no-sql page to "Merge Mango NoSQL data into Mango" by point it at the old_databases/mangoTSDB directory. Assuming you were using NoSQL, then your data would be in your old databases folder, presuming you moved it to be able to start fresh. The incremental backups are of the NoSQL data. You could possibly restore these to get your data back as well.
