comment Why is it good practice to compare checksums when downloading a file?
To add to add to the comment by @0xC0000022L SHA1 is best avoided if security is a major concern already too, though both it and MD5 are perfectly adequate to defend against accidental corruption.

comment How to get the maximum details from a remote host and forcefully get a particular IP?
If the address was given out by dhcp them your dhcp service's logs will probably contain the machine's network card's MAC. You then might be able to find clues using nmap or similar to scan for that MAC and if found looking at what is running on that interface.

comment Monitor server / website load of bandwith
That would only monitor web server input+output, not any other sort of traffic (SSH, database calls if the web server accesses a database on another host, FTP connections, and so forth). Also it won't take into account TCP/IP overheads.

comment Raid 1 across 3 partitions, what does it mean?
@ThatGraemeGuy: With RAID1 over three devices you can lose two devices without the array being toast. You might be thinking of linux's non-nested RAID10 (what IBM RAID controllers call RAID1E) which has the same "can survive one drive lost" fault tolerance as RAID1 over two drives or RAID5 over 3.

comment SQL Server backup compression vs 7zip
Commenting on an old question so it may no longer be relevant to you, but if you are updating off-site copies regularly over the slow link you could try use rsync or similar to create the new instance by updating a copy of the last one. SQL Server does not do "treat the data as a single stream" compression so rsync can sometimes still make significant bandwidth savings when dealing with backups compressed that way (unlike those compressed with 7zip).

comment logrotate output to /dev/null twice?
You can use &>, just make sure that you script explicitly uses bash (i.e. starts #!/bin/bash and not #!/bin/sh) other wise you'll get unexpected errors when you use it elsewhere. If you are feeling paranoid check the bash version early in your scripts to ensure you don't have something prior to version 4 (v4 was released in 2009 so older versions will be rare but you could still encounter them) as I think &> was added in that release.

comment logrotate output to /dev/null twice?
&> is bash specific I believe, where >, 1>, 2>, and so on are more standard. If you know your script will always run in an environment where bash v4+ is installed then yes, you can use &> instead. Logrotate will not be making that assumption though, in fact those scripts probably avoid all bashisms and use /bin/sh (which may or may not be bash, for instance current Debian uses dash by default as it is lighter and more efficient if you don't need bash's extras) instead of /bin/bash specifically.
