There’s lots of misconceptions about backup \u2013 here, I want to present 20 of them:<\/p>\n

    \n
  1. Backup is an IT activity. It’s not<\/strong>. It’s a corporate insurance policy<\/a>.<\/li>\n
  2. Backup is a function of ILM. It’s not<\/strong>. It belongs in ILP, which is not<\/em> the same thing. See “Think Backup Belongs in ILM? Think again<\/a>“.<\/li>\n
  3. Backup is not a production activity. It is<\/strong>. See “Backup is a production activity<\/a>“.<\/li>\n
  4. You don’t need a support contract for your backup environment. You do<\/strong>. See, “Perils of an Icarus support contract<\/a>“.<\/li>\n
  5. You can migrate hardware you’re phasing out of production into backup and DR. You can’t<\/strong>. See, “If you wouldn’t drink it, don’t cook with it<\/a>“.<\/li>\n
  6. Backup failures happen. They don’t<\/strong>. (Potential recovery failures happen.) See, “There is no such thing as a backup failure<\/a>“.<\/li>\n
  7. You can have a backup system without a zero error policy. You can’t<\/strong>. See “No Zero Error Policy? No backup system<\/a>“.<\/li>\n
  8. Backup stops at servers and the occasional desktop. It doesn’t. See “What don’t you backup?<\/a>“, and “But where does the DPA fit in?<\/a>“<\/li>\n
  9. Deduplication can be tacked into a backup solution and immediately solve your capacity problems. It’s not that simple<\/strong>. See “7 common problems with deduplication<\/a>“.<\/li>\n
  10. Inclusive backup policies work. They don’t<\/strong>. See “First, backup everything<\/a>“.<\/li>\n
  11. Backup (and more generally, IT) issues are technology issues. They’re usually not<\/strong>. See, “Technology is rarely the issue<\/a>“.<\/li>\n
  12. Backup capacity issues are solved by adding more capacity first. You should add backup capacity last<\/strong>. See, “A basic data lifecycle<\/a>“, and its follow up posts.<\/li>\n
  13. Archive is backup. It isn’t<\/strong>. See “Archive is not backup<\/a>“.<\/li>\n
  14. A complex backup environment is a good backup environment. Wrong<\/strong>. See, “Of unicorns and horses<\/a>“.<\/li>\n
  15. Backups should be rigorously cost controlled, with every saving aggressively pursued. Wrong<\/strong>. See, “Backups are not about being miserly<\/a>“.<\/li>\n
  16. Cross-site backups allow you to avoid cloning or backup duplication. Nope, definitely not<\/strong>. See, “You can’t escape cloning with cross-site backups<\/a>“.<\/li>\n
  17. Backup sucks. Wrong<\/strong>. It’s actually one of the best jobs you could hope for. See, “Backup does not suck<\/a>“.<\/li>\n
  18. Tape is dead. No, the usage strategy has evolved<\/strong>, that’s all. See, “Direct to tape is dead, long live tape<\/a>“.<\/li>\n
  19. Capacity planning can be done quickly. No, it can’t<\/strong> (unless you have the right tools). See, “Capacity planning \u2013 quickly or properly?<\/a>“<\/li>\n
  20. The dense filesystem problem doesn’t really happen. Yes, it does<\/strong>. See, “In-lab review of the impact of dense filesystems<\/a>“.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
