Leverage the power of regular expressions to fine-tune your backup file exclusion rules. The following are some common regex examples. Please refer to the references below for detailed instructions.
This pattern means any character (the dot) for any number of times (the star) ending with ”.mp3”. The dot in mp3 is escaped with a backslash.
Any pattern beginning with (?i) indicates a case-insensitive search so this example will match both .mp3 and .MP3.
As above, any characters until a directory starting with IMAP followed by any characters. Note that CrashPlan treats all file separators as forward slashes (/).
