# Before using this script, create a repo, note the setting of a password
# kopia repo create filesystem --path C:\kopia_repo --password aaa --file-log-level=info --log-dir=C:\Kopia\Kopia_Logs

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

# useful commands:
# - kopia repo connect filesystem --path C:\kopia_repo -p aaa
# - kopia snap list -all
# - kopia mount all K:
# mounting should be used as non-admin user, weird windows thing
# or one does not see the drive, in that case:
# - 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
