Was restored from backup but a day's work lost. That apart,

perfect . After all, why do we take backups.
Point really is Vulnerability Factor.
No filesystem is perfect. All software has bugs. No version of XFS
"WORKS" (to use your emphasis), they all strive to be perfect but will
fail under some circumstances. The best the XFS team can do is to find
those circumstances, replicate the problem and craft a solution. When
a new combination of circumstances arises (and the fact that the XFS
team is targeting a moving kernel project with significant changes
happening all the time), the XFS code may exhibit a new type of
unwanted behavior. That is life.
If your data is important, you cannot trust any filesystem, on any
operating system, on any piece of hardware, to hold the _sole_ copy of
that data. If you put yourself in that position, then you have only
yourself to blame. It could have been a hardware failure or an
operating system malfunction that caused your data loss as easily as
it could have been XFS.
