SnapLock logging has several advantages.
- SnapLock logging logs all the privileged delete operations that affect a WORM file.
- The SnapLock log resides in the SnapLock Compliance volume. Therefore, you cannot delete the log file until the retention period expires. You can extend the retention period of a log file, but you cannot shorten it.
- The log files are protected from tampering. SnapLock files are not writable by any external applications.
- The SnapLock log file contains the version number; therefore, it is possible to check the compatibility between the log files and log records in different Data ONTAP releases.
- SnapLock log files can be parsed by an XML parser.
