I have 2 questions relating to gzip.

1. I have all of my gzips set to fast instead of best but whenever amdump is
running there will be a gzip --fast and gzip --best for every file that is
in my holding disk. What are the reasons behind this?

2. quoting a colocation facilitys website:
"We use bzip2 instead of gzip for data compression. Unlike gzip, bzip2
compresses data in blocks, which means that in the unlikely event that a
small part of the backup is corrupted, only the affected block is lost. All
other data is still recoverable."

Is this true and if so is there a way to use bzip instead of gzip?  Has
anyone ever looked into this?



Thanks,

Ryan Williams
