Read my post. 5 days ago I said:
"It's interesting to me that encrypted inventory backups had a higher
priority for them than any of the missing features residents have
waiting for. They must not be very confident in their current hosting
service."
Yesterday, Tue Feb 26, 2013 Tranq reported:
"Some regions may be down or malfunctioning. We are currently experiencing hardware problems on a region data host."
The problem they experienced with the region data host justified their concern and the need for multiple redundant inventory backups.
To answer your question, on a grid as unstable as InWorldz, running on questionable hardware, nothing is as important as inventory backups. They acknowledged the same thing by giving it priority.
