I have a question on a particular scenario. Here's the scenario:
Database - Full Recovery Model
1) Full backup on Sat @2300
2) Diff backup everyday @2300
I know that taking Log backups would truncate the Log file. Let's say for the sake of argument that we are not currently taking Log backups. Lets say that the log file gets really big on a Friday, and reaches it's limit. One solution would obviously be to take a backup of the Log file; however, the backup file is huge and running a backup would take a few hours and I need to get this DB up and running as quickly as possible. Second solution would be to switch to the Simple recovery mode which would immediately truncate the log file.
Now I know that in order for me to switch from Simple back to Full, I need to either take a Full Backup, or Differential. My question is, wouldn't doing that interfere with your recovery plan? What's the best practice here?
