Currently when backing up our 3 SQL server database nightly we run full backups. The total size is 820 GB for all the database servers. While the speed of the backup isn't an issue the amount of space it starts taking up is since we need to save at least 1 month of backups. I like to use either incremential or differential backups in backup exec but do not know how reliable incrementials or differentials are are when it comes to a restoring a DB.
Any advice on whether diff or Incremental is the way to go for nightly backups. We can still do the full on the weekend.
