Yep, same here.

We backup about 40 unix servers and 90 Intel servers. Our standard
backup schedule is:
User data:
Daily incremental - 2 month retention
Weekly Full - 1 year retention
System/other data:
Daily incremental - 1 month retention
Weekly Full - 2 month retention
Log files:
Daily incremental - 2 month retention
Weekly Full - 1 year retention
All fulls are duplicated and sent off site weekly for 3 weeks after
which time they are returned and recycled..
