Time Machine completed a verification of your b... | Official Apple Support Communities: "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you."This sucks.

Not so much because of the failure - things go bad, and Apple's Time Machine, which seems to be the moral equivalent of a hardlink farm for snapshots, as so many UNIX systems have, is an especially vulnerable format.
More because, AFAIK, there is no Apple Time Machine way to create a second backup or third backup.
Yeah, yeah, I know: the 3-2-1 Backup Rule, 3 copies, 2 formats, 1 off-site. Fortunately, in addition to Time Machine, I have also been using CrashPlan.
At least I am glad that Apple Time Machine / Time Capsule does verification passes, even if the recovery deletes all backups. Google finds many examples of "I thought that I was ll backed up using Time Machine, but when I tried to restore, the backup was reported to be corrupt." I hope that Crashplan does proper verification. That's what we pay such companies to do.
