# Before using this script, create a repo, note the setting of a password
# kopia repo create filesystem --path C:\kopia_repo --password aaa

# for backblaza b2
# kopia repository create b2 --bucket=rakanishu --key-id=001496285081a7e0000000003 --key=K0016L8FAMRp/F+6ckbXIYpP0UgTky0 --password aaa

# useful commands:
# - kopia repo status
# - kopia repo connect filesystem --path C:\kopia_repo -p aaa
# - kopia snap list --all
# - kopia mount all K:

# mounting might need be executed as non-admin user, weird windows thing
# if one does not see the drive:
# - 'net use' shows path that can be pasted to explorer or browser
#   \\127.0.0.1@51295\DavWWWRoot

# logs location is set C:\Kopia\Kopia_Logs for every command
# if it was not manually set then it would be
# C:\Windows\System32\config\systemprofile\AppData


# to backup multiple targets/paths:
# - [array]$BACKUP_THIS = 'C:\Test','C:\users','C:\blabla'
