Backup Software 2010
Presented by W. Curtis PrestonExecutive Editor & Independent Backup Expert
When I was in the IT Department
• When I started as “backup guy” at $35B company in
1993:
• Tape Drive: QIC 80 (80 MB capacity)
• Tape Drive: Exabyte 8200 (2.5 GB & 256KB/s)
• Biggest Server: 4 GB (‟93), 100 GB (‟96)
• Entire Data Center: 200 GB (‟93), 400 GB (‟96)
• My TIVO now has 5 times the storage my data center did!
• Consulting in backup & recovery since „96
• Author of O‟Reilly‟s Backup & Recovery &
Using SANs and NAS
• Webmaster of BackupCentral.com
• Founder/CEO of Truth in IT

Agenda
• Backup and restore problems
• New backup & restore features
• New products
BACKUP & RESTORE PROBLEMS
So much data, So little time
• Every year we digitize more and more data, creating more and more storage that must be backed up
• Yet the tolerance for traditional backup methods is waning
• No one wants their systems to be inaccessible or slow during backup
• They also want their systems immediately restored with no data loss
SecurityData loss notifications laws:
Requires encryption of personal data by law (MA):
Remote & Mobile Data
Remote & Mobile Data
• Important data
• No (or limited) IT personnel
• Poor bandwidth
• Using tape for remote data is an open invitation for data loss or security issues
• 60-80%* of corporate data resides on PCs and laptops – not on servers

Server Virtualization
Server Virtualization
• 10s to 100s of remote offices in your datacenter (servers w/poor bandwidth)
• The difference is you could be required to simultaneously restore all of these remote offices
• Physics is the problem
• Can only utilize traditional backup techniques for so long
BACKUP & RESTORE FEATURES
Virtual Full Backups
• Available with many products
• Get the power of a full without the data transfer
• Resulting full is the same as a normal full• Restores are the same
• Do not need previous tapes
• Incremental backups based on the full
Backup Software Target Dedupe
• Target dedupe built into backup software allows some of the benefits of appliance dedupe while using generic storage
• Not quite as powerful or scalable as most appliance solutions but may be more affordable for SMBs
Source Dedupe
• Designed to back up remote data over very slow connections• Remote sites
• Mobile systems
• Best suited for environments where bandwidth is a primary concern
• Showing up in many backup products
Dedupe to Tape?
• Concern is that you would need dozens of tapes to restore a single file
• Best used for long term storage of data that you will not frequently restore from
• Must have a good plan for what happens when you do need it
Cloud Backup & Archive
• Not your father‟s Internet backup
• Pricing plans much more affordable, especially for home data
• Perfect for remote data sets, smaller companies, or personal
• Investigate possible future insourcing if it‟s ever possible
Backups Into Archives?
• Typically this is a no-no
• Old grape juice is not wine, and old backups are not archives
• Unless you turn them into archives
• Must give them greater context than typical backup• Full-text search of content of files
• Full-text search against metadata (owner, From:, etc.)
• Separation from host & application requirement
BACKUP & RESTORE PRODUCTS
Disclaimer
• There are hundreds of backup products out there and I have only a few minutes
• Inclusion or exclusion of a product does not equate to me endorsing it or rejecting it
• Products are listed alphabetically
ARCserve
• Aimed at SMBs
• One of the longest-running products
• Investigate new features• Deduplication
• SRM reporting in dashboard
Avamar
• Self-contained source dedupe
• Largest installed base (source)
• Good for remote sites, Vmware
• Gets around any VSS issues, since it can be run inside the VM w/o usual performance issues
Backup Exec

• Investigate new features• OST
• Enterprise vault Engine
• Integrated source/target dedupe
• Work-around for VMware VSS issue
CommVault
• Aimed at SMB & ME, aiming higher
• CommVault Technology Engine
• Backup, Archive, CDP, near-CDP from one engine
• Integrated target dedupe, source is coming
• Backups can offer some archive functionality via full-text search
• Main Commserve runs on Windows
• Depends on VMware for VSS
NetBackup
• Aimed at enterprise
