### Backup Script ###

# Usage:
# * Install VeraCrypt and 7-Zip
# * Replace YourUsername in this script
# * Replace YourBackupLocation in this script
# * Replace YourSuperSafePassword in this script
# * Create five folders named: 1, 2, 3, 4, 5 at your Backup Location 
#   (You can use for example an automatically synced cloud folder (e.g. Dropbox, Onedrive, GDrive) if you want to make sure the backup will be available on hardware loss/damage)

# Now you can run the script to create a new zipped, encrypted backup of your documents folder (or any other location if you change it).
# Once the script created the 5th backup, it will start to remove the oldest backup on the creation of a new one.
# You can add the script to a cronjob/scheduled execution, if you want, e.g., to create a backup every week.

# Get a timestamp for the zip file name
$ak_backup_datestamp = Get-Date -UFormat "%Y-%m-%d_%T" | ForEach-Object {$_ -replace ":", "-"}

# Zip the documents directory
7z.exe a -tzip "C:\Users\YourUsername\Desktop\Documents_Backup_$ak_backup_datestamp.zip" "C:\Users\YourUsername\Documents\*"
