Error description
During an incremental backup, if a file is detected which has had it's 'File Security CRC' changed, it is backed up, despite the fact that option SKIPNTSECURITYCRC=YES is used. Tivoli Storage Manager Versions Affected: 6.4 and 7.1 on Windows platforms Customer/L2 Diagnostics : Here is a service trace extract showing one attributes comparison example performed with the skipntsecuritycrc option set to yes, during an incremental backup At the end we see "Comparison result = ATTRIBS_BACKUP" which is abnormal as only the 'File Security CRC' attribute changed. : fioCmpAttribs(): Entry. : ***** A t r i b T r a c e ***** : fioCmpAttribs(): ignoring attributes: '--N A -------- -- -- -- (0x000000a0)' : fioCmpAttribs(): File Size unchanged since backup : fioCmpAttribs(): Compared FILETIME formated time stamps. : fioCmpAttribs(): File Date/Time unchanged since backup : fioCmpAttribs(): File Attributes unchanged since backup : fioCmpAttribs(): File MSDfs unchanged since backup : fioCmpAttribs(): File Security unchanged since backup : fioCmpAttribs(): File Share unchanged since backup : fioCmpAttribs(): File Security CRC changed since backup <== : fioCmpAttribs(): Named Stream Size unchanged since backup : fioCmpAttribs(): Backup Stream Size unchanged since backup : fioCmpAttribs(): GPFS attributes unchanged since backup : fioCmpAttribs(): Hard Links Hash unchanged since backup fioCmpAttribs(): old attrib's data from build (IBM TSM 7.1.1.3) : ***** A t r i b T r a c e E n d ***** : HSMWIN - fioCmpAttribs: no 'content change' : fioCmpAttribs(): returning ATTRIBS_BACKUP HSMWIN - psHSMWinCmpIncRecallCheck: backup type: 0 HSMWIN - psHSMWinCmpIncRecallCheck: Comparison result = ATTRIBS_BACKUP Initial Impact: Medium Additional Keywords: TSM INCREMENTAL UNNEEDED SKIPNTPERMISSION
Local fix
Use option SKIPNTPERMISSION=YES. This will allow an incremental backup to run without saving the file permissions at all, so it is to be used with care.
