How Scale Computing manages their backup procedures.

This deck also covers:

What are the benefits of backing up to disk versus tape?

How does Scale backup virtual files?

When and how does Scale do incremental versus full backups?

What is Scale’s retention policy for backups?

What’s the difference between RTO and RPO?

Scale-on-Scale : Part 2 of 3 - Backups

  1. 1. How Scale Computing uses Scale's ICOS Storage Webcast 2 of 3 – Using Scale for Backups Bill Waller Director of IT
  2. 2. Agenda Virtual/Physical Backup RTO/RPO Who is Scale? ICOS Why Backup? Scale Production/Backup Disk vs. Tape
  3. 3. Who is Scale? <ul><li>Scale Computing provides scalable, fault-tolerant storage solutions that are affordable and easy-to-use. </li></ul><ul><ul><li>Clustered storage with no single point of failure </li></ul></ul><ul><ul><li>Network RAID 10 for highly available data </li></ul></ul><ul><ul><li>Included remote replication for disaster recovery </li></ul></ul>
  4. 4. Scale ICOS <ul><li>Every Scale storage cluster is powered by ICOS™ Technology: an advanced storage operating system combining powerful features with intelligence that makes storage easy-to-manage, even for novices. </li></ul>Generation 3.0 Storage Scale-Out Architecture Capacity Performance Density Agnostic Unified SAN/NAS No Controllers Thin Provisioning Global Namespace Replication Auto-load balancing Snapshots
  5. 5. Why Backup? <ul><li>Data loss is very expensive </li></ul><ul><ul><li>Hardware Malfunction </li></ul></ul><ul><ul><li>Human Error </li></ul></ul><ul><ul><li>Software Corruption </li></ul></ul><ul><ul><li>Computer Virus </li></ul></ul><ul><ul><li>Natural Disaster </li></ul></ul><ul><li>Government Regulation Compliance </li></ul><ul><ul><li>Sarbanes-Oxley Act (SOA) </li></ul></ul><ul><ul><li>Health Insurance Portability and Accountability Act (HIPAA) </li></ul></ul><ul><ul><li>European Union Data Protection Directive </li></ul></ul><ul><ul><li>Patriot Act </li></ul></ul>Ontrack Survey 2006
  6. 6. Disk vs Tape <ul><li>Disk and Tape both have a place for Backup/DR </li></ul><ul><li>Disk-Based Backup: </li></ul><ul><ul><li>Automated Process (No need to load/rotate media) </li></ul></ul><ul><ul><li>Backups can be faster depending on amount of data backed up </li></ul></ul><ul><ul><li>Restores are almost always faster (no tapes to find and mount) </li></ul></ul><ul><ul><li>Scalable/Highly Available/Redundant storage </li></ul></ul><ul><li>Tape-Based Backup: </li></ul><ul><ul><li>Manual Process (Rotate media) </li></ul></ul><ul><ul><li>Virtually unlimited media size (via libraries) </li></ul></ul><ul><ul><li>Small form factor (transportable) </li></ul></ul><ul><ul><li>Multiple redundant backup sets </li></ul></ul>
  7. 7. RTO and RPO <ul><li>The measurements of data protection are: </li></ul><ul><ul><li>The acceptable amount of time spent to reinstate access to data following a disruption. </li></ul></ul><ul><ul><li>The acceptable amount of data lost in an outage event, measured in time </li></ul></ul>RTO = Recovery Time Objective RPO = Recovery Point Objective
  8. 8. Scale Production/Backup Environment <ul><li>3-Node R4 Scale Storage Cluster (12TB) </li></ul><ul><ul><li>Redundant Power and Network Interface Cards (NICs) </li></ul></ul><ul><li>Scale ’s Production Environment </li></ul><ul><ul><li>100% Virtualized Environment (ESXi 4.1) </li></ul></ul><ul><ul><li>Exchange 2010 (DAG) </li></ul></ul><ul><ul><li>Windows 2008 R2 (Domain Controllers/Active Directory) </li></ul></ul><ul><ul><li>Linux/CentOS (Web Site/MySQL/Atlassian Tools) </li></ul></ul><ul><ul><li>45 Virtual Machines </li></ul></ul><ul><li>Snapshots/Replication </li></ul><ul><li>Symantec BackupExec 2010 </li></ul><ul><ul><li>Backup for Exchange 2010 </li></ul></ul><ul><ul><li>Backup for vmWare ESXi </li></ul></ul>
  9. 9. Physical/Virtual Backups <ul><li>Scale ICOS SnapShots every 6 hours </li></ul><ul><ul><li>Maximum 6 hour RPO (Restore Point Objective) </li></ul></ul><ul><li>Nightly incremental VM backups of all systems </li></ul><ul><ul><li>Maximum 24 hour RPO </li></ul></ul><ul><li>Nightly incremental Exchange backups </li></ul><ul><ul><li>Maximum 24 hour RPO </li></ul></ul><ul><li>Weekend Full Backups </li></ul><ul><li>180-Day Retention of Daily Backups </li></ul><ul><li>Quarterly backups retained </li></ul><ul><ul><li>Q4 backup becomes the annual backup </li></ul></ul>
