BackupBuddy was updated to version 6.3.2.2, from version 6.3.1.3. Changelogs:

6.3.2.2

• Fixed additional text showing in S3 v2 test alert.
• S3 v2 Destination: Fixed problems sending files to new regisions such as Frankfurt in some cases.
• S3 v2 Destination: Fixed problem with using buckets with periods in the name.
• S3 v2 Destination: Bucket is no longer an Advanced Option as it is now reguired to be correct; no longer guessing region. New v4 signature regions require the region be encoded in the signature so it must be known.
• S3 v2 Destination: Fixed write speed calculation being based off time() instead of microtime(true) resulting in less accurate write speed calculations.
• Updated many instances of time() with microtime(true) for better resolution on time calculations that may run faster than 1 second for better resolution.
• Removed majority of styles from legacy jquery ui CSS only used by tooltip.
• force_single_db_file setting now stored in DAT file as it is needed for regenerating integrity check if caches scan if lost.
• Maintenance mode (activated via .maintenance file) now sends a 503 HTTP status code with a retry time of 1 hour to better instruct search engines on how to handle the site being down.
