Powershell Robocopy backup script
Intro
I was looking for ways to backup my photos from my NAS to my homemade backup server so in the event the NAS stops working I would still have the latest files.
After some searching for free ways to do this I used robocopy and powershell to create the following script you can freely download the latest version from my GitHub page.

Pre-reqs that it needed to be able to do:
- Show start and endtime of the backup job
- The duration for performance review
- Amount of copied folders, data and skipped (if any)
- Robocopy end-code results in case of any errors with needed catches (took a while!)
- Source and destination address
- Attach a log file
- Send an e-mail to my admin account
- Have nice feel to it
Robocopy command itself:
robocopy.exe "$src" "$dst" /mir /mt:96 /r:3 /w:3 /np /ts /bytes /xd $exclude /log:"$log"
Explanation of options used:
- /mir tells robocopy to use mirror mode
- /mt:96 maximum of allowed threads increasing or decreasing this results in different end-times
- /r:3 maximum set retry count
- /w:3 maximum set wait time before a retry is executed
- /np shows no progress
- /ts include the timestamp of the source file
- /bytes display progress in bytes for easy calculation
- /xd $exclude exclude files that set in the "$exclude" variable
- /log:"$log" specifies the logfile location by the "$log" variable

Like with all scripts improvements are ongoing.
Recent additions to the script was adding HTML with a clone feel of the Veeam mail report.
I use Veeam to backup my servers and so the look & feel goes hand-in-hand with a few modifications.
An example of the output is:
If an error occurs the green banner changes to red as shown here:
