Multi-user mode dumps can often take 4 to 8 times as long to finish depending on how busy the machine is. Servers are often busy resulting in disk contention between the dump program and file service daemons. Also, depending on your situation, you might want to consider doing a level 0 once a month in single-user mode and the weekly dumps as level 1 in multi-user mode. This should give you enough coverage to recover from catastrophic disk failure with a clean level 0 as well as file retrieval from the multi-user dumps.
