  25. 25. File ArchiveDisk Clone vs.
  26. 26. File ArchiveDisk Clone “mirrors” entire disk copies individual files overwrites
 changed files stores additional copies
 of changed files contains
 one snapshot
 of each file contains
 multiple versions
 of each file
  27. 27. File ArchiveDisk Clone & single snapshot multiple versions
 of entire disk of each file overwrites file history retains file history instant access delayed access fast(er) full restore slow(er) full restore bootable not bootable
 back to work in minutes complete restore may take hours …make great companions.
  28. 28. File ArchiveDisk Clone literally everything all user files hard disk hard disk, server, cloud
 multi-I/O strongly advised multi-I/O nice-to-have
 check partitioning for boot support partitioning scheme irrelevant cable cable, (w-)lan, internet ≥ 1 × source capacity ≥ 2½ × source capacity
 ideally 1½ × source capacity ideally unlimited very fast slow(ish) over network
 use disk seeding for initial backup

  35. 35. pick a strategy for yourself how valuable is your data? is your data “recreatable?” how much downtime can you afford?
  36. 36. oh, and one more thing…
  37. 37. test your backups!test
  38. 38. Disk Clones → boot computer from clone
 launch some applications

 open restored files test your backups! ¹ to new locations —
 do not overwrite the originals! ¹

  39. 39. now go forth and 
 back up your stuff! understand the fundamentals choose a strategy and implement it keep an eye on your backup system rotate media off-site test your backups enjoy
