Syntax►►SKIPACLUPdatecheckNoYes►◄ParametersNo If you specify No, the Tivoli Storage Manager client performs checksum andsize comparisons of the ACL data, before and after backup and duringincremental processing. This is the default.YesIf you specify Yes, the Tivoli Storage Manager client does not performchecksum and size comparisons of the ACL data.ExamplesOptions file:skipaclup yesSnapdiffThe snapdiff option is for backing up NAS/N-Series file server volumes that areNFS or CIFS attached.When used with the incremental command, snapdiff streamlines the incrementalprocess by performing an incremental backup of the files that were reported aschanged by the NetApp Snapshot Difference API, instead of scanning the volumelooking for files that have changed.To enable snapdiff processing, set up a user ID and password on the Tivoli StorageManager client. To set up the client for snapdiff processing, first use the dsmc setpassword command to establish a user ID and password for the snapdiffoperation. The user ID and password must have root authority in order to performNAS/N-Series snapdiff operations. The NAS/N-Series file server volumes that arebeing NFS mounted for snapdiff operation must be exported with both root andread-write access for the AIX host being used.Use this option with an incremental backup of a NAS filer volume instead of asimple incremental or incremental with snapshotroot whenever the NAS filer isrunning ONTAP V7.3 or later, for performance reasons. Do not use the snapdiffand snapshotroot options together.Restriction: Incremental backup using snapshot difference is only available withthe 64-bit Tivoli Storage Manager client for AIX.The first time you perform an incremental backup with this option, a snapshot iscreated (the base snapshot) and a traditional incremental backup is performedusing this snapshot as the source. The name of the snapshot that is created isrecorded in the Tivoli Storage Manager database.The second time an incremental backup is run with this option, a newer snapshotis either created or an existing one is used to find the differences between thesetwo snapshots. This second snapshot is called the diffsnapshot. Tivoli StorageManager then incrementally backs up the files reported as changed by snapdiff to398 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
the Tivoli Storage Manager server. The file space selected for snapdiff processingmust be mapped or mounted to the root of the volume. You cannot use thesnapdiff option for any file space that is not mounted or mapped to the root of thevolume. After backing up data using the snapdiff option, the snapshot that wasused as the base snapshot is deleted from the .snapshot directory. Tivoli StorageManager does not delete the snapshot if it was not created by Tivoli StorageManager. You can also perform a snapdiff incremental backup with the-DiffSnapShot=Latest option.For NAS and N-Series filers running ONTAP 7.3 or later, you can use the snapdiffoption when performing a full volume incremental backup. Using this optionreduces memory usage and speeds up the processing. However, similar to usingthe incremental-by-date method, the following considerations and situations apply:vvvvvvA file is excluded due to an exclude rule in the include-exclude file. TivoliStorage Manager performs a backup of the current snapshot with that excluderule in effect. This happens when you have not made changes to the file, butyou have removed the rule that excluded the file. The snapdiff option does notdetect this include-exclude change because it only detects file changes betweentwo snapshots.If you have added an include statement to the option file, that include optionwill not take effect unless the snapdiff option detects that the file has changed.This is because Tivoli Storage Manager does not inspect each file on the volumeduring backup.You have used the dsmc delete backup command to explicitly delete a file fromthe Tivoli Storage Manager inventory. The snapdiff option does not detect that afile has been manually deleted from Tivoli Storage Manager. Therefore, the fileremains unprotected in Tivoli Storage Manager storage until it is changed on thevolume and the change is detected by the snapdiff option, signalling TivoliStorage Manager to back it up again.Policy changes such as changing the policy from mode=modified to mode=absoluteare not detected.The entire file space is deleted from the Tivoli Storage Manager inventory. Thiscauses the snapdiff option to create a new snapshot to use as the source, and afull incremental backup will be performed.The snapdiff option controls what constitutes a changed object.Note: In the list of options used by the traditional incremental command, the lastcolumn shows each option’s interaction with the snapdiff option. The definitions ofvalid, not valid, and no effect are:Valid Processing runs normally when the option is used.Not validIf the option is used with the snapdiff option, an error message isgenerated.No effectThe option can be used, but it is ignored.Table 66.
