# The following are a series of dump format magic numbers. Each one
|
|
# corresponds to a drastically different dump format. The first on is
|
|
# the original dump format on a 4.1 BSD or earlier file system. The
|
|
# second marks the change between the 4.1 file system and the 4.2 file
|
|
# system. The Third marks the changing of the block size from 1K
|
|
# to 2K to be compatible with an IDC file system. The fourth indicates
|
|
# a dump that is dependent on Convex Storage Manager, because data in
|
|
# secondary storage is not physically contained within the dump.
|
|
# The restore program uses these number to determine how the data is
|
|
# to be extracted.
