TSM-Progressive backup•ONLY new or changed files backed up•NO redundant backups•Restores don’t require the same file to be restored multiple times•NO wasteful weekly full backups and their dependent incremental/differential•Data tracked at file level•Accurate restores

TCP/IP
Data transfer(SCSI/FC)
•Minimizes network traffic and transfer data outboard of the TSM client and server
Backups/restores direct to libraryNo LAN data traffic
•Uses Network Data Management Protocol (NDMP) to perform high-performance, scalable backups and of restores
•TSM also supports NFS/CIFS backup of NAS devices Control

Sharing Tape Devices between multiple servers for backup purposes

Advantages:Lower tape system costs through sharingLower media costs
Disadvantages:Administration of multiple backup serversCareful scheduling to avoid drive contention

TSM Client and Storage Agent
Client (application host) discovers low-level mapping for data, and passes to third party data moverAll data movement is ‘out-board’ of the clientXCOPY services can exist in various SAN devices
Advantages:Requires no CP cycles on client for backup I/OCan work well for non-file objects (eg. volumes)
Disadvantages:XCOPY specification still evolvingNot transparent to application/databaseDifficult file-to-block mappingLimited platform, device and database supportUnproven performance/reliabilityVolume level backup / restores
Also called ‘3rd party copy’ or SCSI Extended Copy (XCOPY)

Lan-free backup has client storage agent send data directly to tape or disk
Advantages:•Client data can be local or SAN-attached•Transparent to application/database•Takes backup traffic off the LAN•Reduces CP cycles on backup server (no I/O)•Faster speed (usually)•Only one backup server needs administration
Disadvantages:•Still requires CP cycles on client for backup I/O•Careful scheduling to avoid tape drive contention (or exploit disk pooling with some solutions)

Fire wall supportFire wall supportAdvanced backup, recovery & web client
support through firewalls
•API-based solution enables TSM server to
communicate directly with the target clients that
are to be protected
Requires the assignment of only two
firewall portsIrrespective of the # of target servers and
clients that are to be protected
First port allows TSM server & clients TCP/IP
communication
Second port enables scheduling between TSM
server & clients
Optional third port enable the administrative
Web interface

Tivoli Storage Manager –vs- Veritas Tivoli Storage Manager –vs- Veritas NetBackupNetBackup
IBM Tivoli Storage Manager Veritas NetBackup
Utilizes powerful relational database to track meta data
Uses flat file catalog that can’t span filesystems
Only needs to back up new and changed files – progressive backup
Must do weekly full backups
Policy changes retroactively applied to previously backed up/archived data
Policies changes are not retroactive – must REBACKUP data
Mobile backup function built in Additional product
Archived files are retained for long term storage based on management policy
Archive is just a backed up file followed by deletion of original file
DR planning built in and automated Additional manual service
Flexibility to move data from one type of media to another
No migration capability
Able to reclaim dead space on local tapes No tape reclamation capabilities
Restores just version of files needed Wastefully restores full + incrementals
Fastest Backup Cycle 40% Faster than Veritas NetBackupFastest Restores 87% Faster than Veritas NetBackupBest Tape and Disk Utilization 4x fewer tapes and 44% less disk than Veritas NetBackup
