Nodequeue

"The Nodequeue module allows users to collect nodes in an arbitrarily ordered list. The order in the list can be used for a any purpose, such as: A block listing teasers for the five top news stories on a site A user’s favorite music albums A group of favorite from which one is randomly displayed Nodequeue provides a simple drag-and-drop interface to manually order any queue. Additionally, it allows nodes to be added and removed from queues

Backup and Migrate

If hosting on Acquia or Pantheon, I don't use this module because I can get backups from their dashboards. But sometimes, you don't have all the control you wish you did, and this module comes in handy... Easily create db dumps that automatically exclude cache contents. You can setup a regular backup schedule. It also has the ability to restore from backups, but I haven't used that functionality in years.

Location

It's been awhile since I've used it. It provides a location field. From what I remember, it's a little buggy. Quote from Mediacurrent, "Address Field - I used to use the Location module fairly often and in early Drupal 7 I used this module. I tend to like the Geofield module a lot more than these particular modules." http://www.mediacurrent.com/blog/top-drupal-7-modules-winter-2014-edition

Address Field

Works well with Geocoder. Used in Drupal Commerce. Quote from Mediacurrent: "Address Field - I used to use the Location module fairly often and in early Drupal 7 I used this module.

Search API

Amazing module that integrates with both the db and solr (it also supports other backends but some contrib modules don't.)

Pathologic

"Pathologic is an input filter which can correct paths in links and images in your Drupal content in situations which would otherwise cause them to “break;” for example, if the URL of the site changes, or the content was moved to a different server. Pathologic can also solve the problem of missing images and broken links in your site’s RSS feeds."
