Debugging security with sectrace

A new command called "sectrace" can help debug security problems (e.g. user cannot chown a file with NT ACL).

sectrace add -a -path /vol/software

will produce meesages such as these:

Sun Feb 1 13:10:52 IST [jim: sectrace.filter.allowed:info]: [sectrace index: 2] Access allowed because 'Synchronize, Read Attributes' permission (0x100080) is granted on file or directory (Access allowed by an explicit access control entry) - Status: 1:58720452:0:0 - 10.1.20.107 - NT user name: support\administrator - UNIX user name: root(0) - Qtree security style is NTFS and NT ACL is set on file/directory - Path: /vol/software/

Typically there is no need to use -a since you only want to debug DENY replies.

Migrate Data with Robocopy

robocopy C:\ \\\ /MIR /COPYALL /Z /LOG:C:\Robocopy.txt /R:0 /W:0 /NP /XD RECYCLER "System Volume Information" ~snapshot

Some explanations:

• /Z - Restartable Mode - If Robocopy is stopped, then restarted, partially copied files are picked up and incrementally copied.
• /B - Backup Mode - In some cases it is advised to also add the /B (Backup Mode) option to copy files in backup mode. This option leverages the Windows NT "backup mode" feature, allowing files to be copied using the Backup Operator rights.
