It's a false dichotomy[1], but sums up the trade-off between those two options well enough. The last "hacker" who tried to delete everything on my system was a 5.25in floppy. So, I'm biased towards the other case. [1] Third option: choose push or pull, and ALSO make off-site read-only backups of the backup server every once in a while.
