Carbon Copy Cloner logs its activity to a file located at /Library/Logs/CCC.log. You can use this log to verify the productivity of your scheduled tasks. To view CCC's log file, choose "CCC Log" from the Window menu. Beta versions of CCC will produce more output than non-beta versions. Additionally, you can manually enable debug logging by choosing "Enable Debug Output" from the Help menu.
Debugging output is only useful to the developer, so don't enable debug logging unless instructed to do so for support purposes. CCC imposes a size limit of 512KB on the log file. When this limit is reached, the log is rolled over.
Comment on the "Data copied" figure reported in the CCC.log
This value indicates the data written that was actually consumed as disk space. For example, suppose you copy a single file that occupies a single 4Kb block (4,096 bytes) on the disk, but that file fills only 32 bytes of that block. This value represents the accumulation of those 32 byte values. This value will *not* correspond to the value of disk usage indicated in Disk Utility (not even close in most cases), Disk Utility reports the number of blocks occupied multiplied by the size of the block.
