Adding my own experience: I have to R&C the Access back-end about 4 times per day. After 15 years of rock solid that is very hard to take.
Today I found that 1500 records were missing in a table, and the relationship between this table and a child table had been removed. All without R&C logging or showing any information about that. Would have been good to know!
Fortunately I have been taking 15 minute backups for the last several months, so I could go back 2 days and fix it. Took me an hour, all said and done. An hour I could have spent on a billable project. Maybe I should send MSFT the bill Woo-ha-ha-ha <more
