Common Dataxform Examples

Estimating the dataxform Runtime Period

Please Note:

Estimating the dataxform Runtime Period

Rekeying the files in a GuardPoint can take a long time if there are thousands of files to be rekeyed. The --deep_scan argument on the dataxform command simulates and estimate how long a dataxform session will take on a specified GuardPoint. Enter all the arguments that you would normally use for the dataxform session, and assign the rekey policy to the GuardPoint, so dataxform accurately simulates the actual rekey process.

--deep_scan is CPU and I/O intensive. Expect a drop in system performance while running --deep_scan. It can take a long time to complete--enough so that for very small file systems, you are better off running dataxform directly rather than trying to estimate how long it will take with the --deep_scan option.

The following shows a simple dataxform command line session with the --deep_scan argument.

# dataxform --deep_scan --gp /opt/apps/dx4

Checking if data transform is supported for guard point /opt/apps/dx4
Data transformation is supported on /opt/apps/dx4
About to perform a deep scan of the guard point
-- To enable consistent results, do not access the guard point during
   the scan
-- Transformation simulations will be performed, which may take some time

Status information for directories in guard point
Directory /opt/apps/dx4/ab_dir/ contains 140 files (1 GB)
Directory /opt/apps/dx4/ac_dir/ contains 734 files (21 GB)
Directory /opt/apps/dx4/aa_dir/ contains 40 files (15 MB)
Directory /opt/apps/dx4/ad_dir/ contains 37 files (70 MB)
Directory /opt/apps/dx4/ contains 46 files (915 MB)
Scan found 997 files (23 GB) in 5 directories for guard point /opt/apps/dx4
Estimated data transformation time for /opt/apps/dx4 is 1h 13m 6s
-- This is an estimated time using actual data
   transformations on test files
-- The actual transformation time may be more or less than this estimate

The second line of the --deep_scan output in the example above is "Data transformation is supported on /opt/apps/dx4". This line is displayed when the directory being scanned is an active GuardPoint with a rekey policy. This line is not displayed when the directory being scanned is a regular directory, a disabled GuardPoint, or an active GuardPoint with a regular, non-rekey policy.

The --deep_scan results are also echoed to /var/log/vormetric/vordxf-_path_usr.log and forwarded to the Logs windows.
