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

Two typesLibrary sharing onlyDynamic drive sharing

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

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
