Networker 6 TSM 5.1 datazone consists of a single NetWorker server, NetWorker clients and storage nodes client any system with data to be backed up server contains the client file index and the media database storage node hosts one or more backup devices (tape or other media) save set originates from a single client and may consist of a single file, a directory, a file system, or a partition. Each backup run creates a new save set client file index contains detailed information about each save set such as the filename of each file stored, time of back up, size, permissions, ownership, etc. Info is stored in flat files. Can be rebuilt from scratch. media database maps the save sets to the volumes where they are stored, stores the browse and retention policies for each save set, and maintains tracking information for all storage volumes. Info is stored in flag files. Can be rebuilt from scratch. browse policy determines how long file entries are maintained in the client file index retention policy determines how long save sets are stored on backup media volume pool a specific collection of volumes to Storage Pool which the NetWorker server writes data. The server uses pools of volumes to sort and store data. The configuration settings for each pool act as filters that tell the server which volumes should receive specific data save set consolidation Save set consolidation merges a new level 1 backup with the last Full backup of a save set to create a new Full backup. cloning process of creating duplicates of complete volumes or individual save sets. staging allows save set data to be migration transferred from one storage medium to another. save set "REPAIRDISK" backup: full Backs up all files, regardless of whether or not they have changed. backup: Level 1-9 Backs up files that have changed since the last lowered numbered backup. backup: Incremental Backs up files that have changed since the last backup, regardless of level. backup: Consolidated Backs up all data that has changed since last full backup and subsequently merges these changes with the last full backup. savegroup list of clients to be backed up in a scheduled run multiplexing interleaves data from more than one save set into each record written to a storage volume. server parallelism parameter to control the number of concurrent data streams that a server will accept. client parallelism parameter to control the maximum number of concurrent data streams a client will send. directives part of a client configuration to define compression, excryption and/or password protection directed recovery recovery of data to a client other than the originating client.

X Networker 6 TSM 5.1 Legato depends on the change flag of the file system. Tivoli depends on the info in the database to identify changed files The client file index is backed up immediately after a client’s save sets finish. If the NetWorker server is part of a regularly scheduled backup group, a bootstrap is created only when that backup group runs. If it is not part of a regular backup group, a bootstrap is created at the end of every savegrp. After a browse policy has expired a save set can only be restore in its entirety Files recreated through index-based recovery appear “new” to the client- side save program, the first time they are encountered during a backup. Newly recovered files are backed up on the next scheduled backup and inherit the browse policy in effect for the client at the time of the backup. Save set recovery lacks the file handling features that are built in to index-based recovery, so care must be taken to recover save sets in order. Client licensing Purchase ClientPak's for every License number of clients to backup operating system - no limitation regarding OS You can't cache staged save sets in the original storage medium Legatos file and media index files run programs to check integrity of are more susceptible to power you index files and media database outages and server crashes If the filesystem that contains the indexes gets full, the NetWorker server is unable to access the media database and is thus unable to access and recover data. Unless you configure the server to control the size of the online indexes by using browse and retention policies, they continue to grow until they exceed the capacity of the filesystem. No thresholds available Renaming a client is a 8 step process No storage volume is available for Needs more tapes than TSM for the tapes with lot of expired space can relabeling until, at a minimum, all same amount of data be reclaimed save sets on the storage volume have exceeded their retention policies.
