Archiving tags in WinCC

Hi there
1)How far you can go back in trend view depends upon following:
a)How much hard disk capacity you have and how much you have configured.
b)How frequently you are archiving the particular tag
If you are archiving the less frequently and you have alloted enough space then you can go back as possible (a year or two year), like that

2)That alarm will go after either the segment time is complete or when alloted disk space is filled.In both cases overlapping starts, and old data is gone forever.

Also read "Archiving Process Value" in WinCC help.
