Cloudundancy is a cross-platform C++ command line program for quickly copying a configurable list of files and folders to a configurable list of destination folders to achieve cloud-redundant and device-redundant backups of files.

For example, on Windows in a Cloudundancy.ini file, destination folders can be configured to be automatic-cloud-uploading Google Drive and Microsoft OneDrive folders C:\GoogleDrive\CloudundancyBackups and C:\OneDrive\CloudundancyBackups. Double USB backups can also be achieved by adding USB drive paths such as E:\CloudundancyBackups and F:\CloudundancyBackups to a Cloudundancy.ini file.

On Linux, a Bash script can be written to run Google Drive command line drive push from ~/googledrive after having run Cloudundancy to copy files to ~/googledrive.

Cloudundancy command line usage

Cloudundancy v1.0.0
Copies configurable file and folder paths to configurable file and folder paths.
For example, on Windows, destination folder paths can be set to C:\GoogleDrive and C:\OneDrive
to achieve cloud-redundant backups by way of automatic cloud uploading.

Usage:
   cloudundancy example-linux-ini-file
   cloudundancy example-windows-ini-file
   cloudundancy copy-files-to-multiple-folders
      --ini-file=<FilePath> [--delete-destination-folders-first]
   cloudundancy 7zip-files-then-copy-the-7zip-file-to-multiple-folders
      --ini-file-to-copy-files-to-7zip-staging-folder=<FilePath>
      --7zip-staging-folder=<FolderPath>
      --ini-file-to-copy-7zip-file-from-staging-folder-to-multiple-folders=<FilePath>

Cloudundancy program modes

example-linux-ini-file

Program mode example-linux-ini-file prints an example Linux Cloudundancy .ini file which shows how to achieve triple backups of files to one GitHub repo folder and two USB drives:

example-windows-ini-file

Program mode example-windows-ini-file prints an example Windows Cloudundancy .ini file which shows how to achieve quintuple backups of files to two automatic cloud-uploading folders (C:\GoogleDrive and C:\OneDrive), one GitHub repo folder (C:\GitHubRepos), and two USB drives (D: and E:).

[DestinationFolders]
# Cloud-redundant backups to Google's cloud, Microsoft's cloud, and GitHub's cloud
C:\GoogleDrive\CloudundancyBackups
C:\OneDrive\CloudundancyBackups
C:\GitHubRepos\CloudundancyBackups

# Device-redundant backups to USB drive D: and USB drive E:
D:\CloudundancyBackups

[SourceFilesAndFolders]
# In the [SourceFilesAndFolders] section, the line format is:
# SourceFileOrFolderPath -> RelativeDestinationFolderPath

# Critical files to backup

copy-files-to-multiple-folders

cloudundancy copy-files-to-multiple-folders
   --ini-file=<CloudundancyIniFilePath> [--delete-destination-folders-first]

Program mode copy-files-to-multiple-folders copies files and folders listed in a Cloudundancy.ini file to multiple destination folders.

Most notably, destination folders can be configured to automatic cloud-uploading Google Drive and Microsoft OneDrive folders on Windows for achieving cloud-redundant file backups.

Console output on Linux for cloudundancy copy-files-to-multiple-folders --ini-file=/code/dotfiles/LinuxCloudundancy.ini --delete-destination-folders-first:

As an example on Windows, imagine the following folder structure at C:\CloudundancyTesting:

With Cloudundancy.ini being as follows to instruct Cloudundancy to backup business-critical files and folders present in C:\CloudundancyTesting, except for file paths containing case-sensitive substrings ignored_filename or .ignored_file_extension:

Console output for Cloudundancy.exe copy-files-to-multiple-folders --ini-file=C:\CloudundancyTesting\Cloudundancy.ini --delete-destination-folders-first:

7zip-files-then-copy-the-7zip-file-to-multiple-folders

cloudundancy 7zip-files-then-copy-the-7zip-file-to-multiple-folders
   --ini-file-to-copy-files-to-7zip-staging-folder=<CloudundancyIniFilePath>
   --7zip-staging-folder=<FolderPath>
   --ini-file-to-copy-7zip-file-from-staging-folder-to-multiple-folders=<CloudundancyIniFilePath>

Program mode 7zip-files-then-copy-the-7zip-file-to-multiple-folders performs the following steps to backup files to a .7z file and then copy the .7z file to multiple destination folders:

1. Deletes the 7-Zip staging folder specified with --7zip-staging-folder.
2. Copies [SourceFilesAndFolders] listed in Cloudundancy.ini file --ini-file-to-copy-files-to-7zip-staging-folder to the 7-Zip staging folder.

Example --ini-file-to-copy-files-to-7zip-staging-folder:

3. Runs executable 7z on the PATH to 7-Zip the contents of --7zip-staging-folder to a .7z file written to folder <7ZipStagingFolder>\7ZipFile with file name CloudundancyBackup_YYYY-MM-DDTHH-MM-SS.7z.
4. Copies the .7z file to [DestinationFolders] listed in Cloudundancy.ini file --ini-file-to-copy-7zip-file-from-staging-folder-to-multiple-folders.

Example --ini-file-to-copy-7zip-file-from-staging-folder-to-multiple-folders:

As an example, consider the following folder structure:

Console output on Windows for the following Cloudundancy 7-zip command line:

Cloudundancy.exe 7zip-files-then-copy-the-7zip-file-to-multiple-folders
   --ini-file-to-copy-files-to-7zip-staging-folder=C:\Cloudundancy7ZipTesting\CodeFolderTo7ZipStagingFolderCopyingStep.ini
   --7zip-staging-folder=C:\Cloudundancy7ZipTesting\7ZipStagingFolder
   --ini-file-to-copy-7zip-file-from-staging-folder-to-multiple-folders=C:\Cloudundancy7ZipTesting\7ZipFileToGoogleDriveAndOneDriveCopyingStep.ini
