Parameters

no
The backup-archive client does not check the change time (ctime attribute) during a backup operation. This value is the default.
yes
The backup-archive client checks the change time (ctime attribute) during a backup operation. If the ctime attribute changed since the last backup operation, the ctime attribute is updated on the IBM Spectrum Protect server. The object is not backed up unless it has either ACLs or extended attributes. The client checks files and directories.
