Hi Eric, On UNIX and Linux systems, if only file permissions have changed, then the latest backup copy is updated with the changed permissions; it is not backed up again in full.
>From the online documentation at http://www-01.ibm.com/support/knowledgecenter/SSGSG7_7.1.1/com.ibm.itsm.client.doc/c_bac_fullpart.html: Files are backed up when any of the following attributes change: * File size * Date or time of last modification * Extended Attributes * Access Control List If only the following attributes change, the attributes are updated on the Tivoli Storage Manager server, but the file is not backed up: * File owner * File permissions <== This one * Inode * Group ID * Change time (ctime) attribute. See the updatectime option for details. (AIX and Linux only) * Icon location (Mac OS X only) * Type or creator (Mac OS X only) Best regards, - Andy ____________________________________________________________________________ Andrew Raibeck | Tivoli Storage Manager Level 3 Technical Lead | [email protected] IBM Tivoli Storage Manager links: Product support: http://www.ibm.com/support/entry/portal/Overview/Software/Tivoli/Tivoli_Storage_Manager Online documentation: http://www.ibm.com/support/knowledgecenter/SSGSG7/welcome Product Wiki: https://www.ibm.com/developerworks/community/wikis/home/wiki/Tivoli%20Storage%20Manager "ADSM: Dist Stor Manager" <[email protected]> wrote on 2015-03-12 10:25:47: > From: "Loon, EJ van (ITOPT3) - KLM" <[email protected]> > To: [email protected] > Date: 2015-03-12 10:26 > Subject: Linux permissions not restored > Sent by: "ADSM: Dist Stor Manager" <[email protected]> > > Hi guys! > Yesterday someone accidentally changed permissions on one of our > Lotus Notes servers.
