Jochen’s backup setup

pick a strategy for yourself

how valuable is your data? is your data “recreatable?” how much downtime can you afford?

oh, and one more thing…

test your backups!test

Disk Clones → boot computer from clone launch some applications open some files

File Archives → restore some files & apps launch restored apps

open restored files

test your backups!

¹ to new locations —do not overwrite the originals!

¹

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�� the�� Peace�� of�� Mind!
