comment /etc/cron.daily/foo : Send email to a particular user instead of root?
Note for CentOS 6.5 (cronie) users: /etc/crontab does not specify defaults.

comment /etc/crontab permissions
"/etc/crontab is the main - crontab - resposible for triggering cron.daily, weekly" - That is only true for Debian. See the crond(8) manpage.

comment What's faster, dd 1.5TB or rsync 500GB?
It also makes sense that, if the disk were full (1.5TB of actual non-sparse data), rsync would be slower than dd.

comment What's faster, dd 1.5TB or rsync 500GB?
My buddy kormoc tells me: "kernel <-> userspace is just memory copies. It copies way faster then the disk actually responds, so it's almost free. DD still does the kernel -> user -> kernel layer changes as well. dd does not run in kernel space."

Awesome, thanks! For some reason I thought moving data between kernel-space and user-space was expensive, and dd avoids this, but I might be making that up.

comment Are multiple @daily crontab entries processed in order, serially?
@daily is slightly different than /etc/cron.daily. The former is an alternate syntax for use in a crontab. Also have a look at run-parts. My system uses run-parts to run programs in /etc/cron.daily. According to the run-parts(8) manpage, "Files are run in the lexical sort order of their names...".

@jw013 and Kevin: agreed, but that's not my question.

This helps, thanks. I agree @jw013's suggestion is valid, but that's not the question I asked. I guess I'll have to consult the actual source for the definitive answer, since this is probably, indeed, implementation-specific.

Indeed, thanks! I missed the dupe in searches I did before posting.
