Backup & Recovery: Time is Never an Ally Chris Schin Zetta VP Products February 2012
Why do you do backups? Degree of difficulty Site disaster Frequency of Occurrence Server recovery Revert to older file version Replace deleted file Other Dimensions Cost Complexity Backup window 2
Data Protection is not a Luxury Hardware failures Software failures Human error Malware Natural disasters Manmade disasters Sabotage 74% of companies have had a data loss incident in the past 2 years 3
Recoverability Evolution of Data Protection Tape Disk D-D-T Appliance to cloud Cloud only 4
Top Data Protection Issues Inability to recover and restore data Exceeding recovery time objectives Complex recovery and restore processes Inadequate versioning Data security Cost 5
Inability to Recover and Restore Data Issues Data at rest failures Silent data corruption Tape failures Data loss missing tape Out-of-date / support hardware Seven-year old tape Lack of restore/validation testing Lack of process testing Remedies Data scrubbing / checking hardware, data hashing Strong RAID (disk) Multiple data copies (tapes) Audited, secure processes Quarterly restore testing 6
Exceeding Recovery Time Objectives Issues Time to recall tape(s) Time to process multiple sets of data (full backup plus incrementals) Unprioritized recovery order Media errors / mistakes Start over Remedies Disk-based recovery Pre-planned recovery priority Test / practice recovery 7
Complex recovery and restore processes Issues Manual handling of tape or removable disk Offsiting of removable media Full plus incremental recover steps Grandfather Father Son Unrehearsed, untested processes Remedies Disk-based recovery Synthetic full backups Documentation and training Quarterly testing 8
Inadequate Versioning Issues Backup data is too old most critical/active data is today s On-premises snapshots used as backup Remedies More frequent full backups More frequent incremental backups Offsite / off-premises snapshots 9
Data Security Issues Lost / stolen portable media Mandated public notification Fines $$$ Hacked communications Remedies Encrypted portable media Encrypted data transfers At-rest encryption for public storage services Audited (e.g., SAS 70 Type II) procedures / processes 10
Cost Issues Optimizing recovery time adds expense Disk to tape $ Disk to disk $$$ Providing fast recovery PLUS disaster protection adds expense Disk-to-disk-tape $$$$ Improving granularity adds expense $ Remedies Categorize data and recovery needs (will add complexity) or Online Backup 11
An Alternative Approach Online Backup using Sync and Replicate Replicate data to an online, mountable storage service Automatically sync changes with the primary data set (no backups! ) Selectable frequency Create granular, cloud-based restore points Hourly, daily, weekly 12
Data Protection Using Online Backup Benefits Offsite, yet online, mountable and browsable (not on tape!) Continually verifiable just mount and read Available for anytime draw down of individual files, folders, and directories Ready for immediate failover Secured, protected and managed by experts 13
