The -maxsize max option sets the maximum size of the Change Journal in
bytes. The highest possible value is 4 GB (4294967296 bytes). Any specified
value greater than 4 GB will be rounded down to 4 GB. Note that a reasonable
size for a 100 GB drive is an 85 MB Change Journal.
The -delta del option specifies the size in bytes to be purged from the Change
Journal when it reaches its maximum size. We recommend the value be
approximately one-eighth to one-quarter the value of the maximum size but not
greater than one quarter the size of the maximum size. This value may be
automatically adjusted to better correspond to the volume cluster size.
-stop
Stops the Change Journal asynchronously.
The -wait specifies that the Change Journal will be stopped synchronously. The
call returns only after the Change Journal has been deleted.
-query
Queries the status of the Change Journal.
NOTES
If the -start option is specified and the Change Journal is already active, the
Change Journal is adjusted to the value of the maximum size and delta. Note that
these values can only be adjusted to increase.
When starting the Change Journal, if you not specify -maxsize and -delta, or
specify 0 for these parameters, the system chooses a default value based on the
volume size.
The command line tool gets the input either directly from the command line or from
a file. Using input directly from the command line allows only one operation at a
time. To perform more than one operation, create a file using the -file filename
option and use it as an input. Note that the commands in the file are executed from
top to bottom.
As an alternative to the Data Protector omnicjutil command, you can also use
the Windows fsutil command for administering the Change Journal.
EXAMPLES
To start the Change Journal with the maximum size of 8 MB (in bytes) and specify
the size of 1 MB (in bytes) to be purged from the Change Journal when it reaches
the specified maximum size, run:
cjutil -start —maxsize 8388608 —delta 1048576
