UNCONFIRMED  errors and comments from readers: 


(4) End of the paragraph titled "Schadenfreude";

2 letters are swaped in the word "chpater"

"later in this chpater" Should be
"later in this chapter"


[66] 1st paragraph, definition of "Incremental";
The definition for "Incremental" is incorrect; it should end as follows:
"... and mark them as backed up".
(i.e. omit the "do not"


{90} 1st paragraph, opening sentence;
"The v option is used ..." should read
"The s option is used ...", consistent with the paragraph heading.


(105) last line of last paragraph;
"value if usually 20 ..." should read
"value is usually 20 ..."


{106} "Use GNU tar if You Can" box, last bullet, last line;
"... tar -create -verbose -file." should read
"... tar --create --verbose --file."
(i.e. consecutive dashes, not single dashes).


(115) 3rd paragraph, last sentence;
", authenticating using rsh, or ssh if the RSYNC_RSH variable had been set to ssh:" should read
", authenticating using ssh, or rsh if the RSYNC_RSH variable had been set to rsh:"
(i.e. swap rsh with ssh, and ssh with rsh)


[117] 2nd paragraph;
Contrary to paragraph #2, the first two rsync commands on this page do not do the same thing. The outcome
of the first command is correctly described in paragraph 1, but the second command results in a different
destination tree (/backup/home/home).


{154} Installing BackupPC;
The download website is incorrect and should be changed from "http://backuppc.sourceforce.net/" to
"http://backuppc.sourceforge.net/".


(629) last paragraph;
in the PDF version, i can read :
"On a Unix/Linux machine, ps–ef would show something like the following:
Need a process list from a PostgreSQL machine"

On my database server, i've :
