When you need to convert a pdf file to a word document, just type online pdf to word in google. Choose the one that allows you to donwload your destination file right away. (Well, your choice is up to your preference. I'm just saying that because I do not want to wait for email, etc. Of course, my only other requirement is that it's free!)
In case your pdf turns out to be created from an image (the pdf was scan as a picture and converted into pdf), you need ocr pdf.
Here are what I found from google.

easiest way for backup?
Reflect (free) by Macrium
http://www.macrium.com/reflectfree.aspx
How often you wish you can easily backup your data? The program will update your backup only the changes. All you need is
1. install the program.
2. create a profile (e.g. one directory per profile).
3. run the profile.
On your next use...
4. run the profile.
One tip, though, is that I usually prefer to confirm that the profile is "keep the file if not found on source". i.e. if you accidentally delete a file you still need to keep, the backup copy will not be deleted when you perform the backup.
Of course, the backup looks just like a regular directory on another drive. You can copy it back anytime. My personal thought is that I prefer to keep those I delete because I only keep current files on my present drive. My backup is like an archive.

Spiltting .zip by winzip
I ran into a situation where gmail does not allow me to have any attachment larger than 25MB. It recommended me to use (google) drive instead.
Because some of my recipient does not use gmail, I waste a lot of time recalling what are my options.
Winrar only performs the split for .rar, so does .7p for 7zip. I, thus, have to go back to Winzip. I totally forgot that the extension of the remaining zip files are not .zip but .zXX where XX is the sequence of the split.
Now you know what to do when you need to split a file or a folder.
