FileSync is very basic implementation of .Net GoogleDriveAPI v3. It uploads a single file to Google Drive cloud storage, using a Google service account. It grants permission to this file to another Google Drive account.

filesync's Issues

Uprade to .NET 5 and check for security updates

Add Create Remote Folder Function

Add support to Grant Permissions for More Than one GoogleAccount

Remove Win32 dependency

In order to run in a alpine linux docker container the win32 dependency from Drive.Api has to be removed.

using Microsoft.Win32;

        // tries to figure out the mime type of the file.
        private static string GetMimeType(string fileName)
        {
            string mimeType = "application/unknown";
            string ext = System.IO.Path.GetExtension(fileName).ToLower();
            //TODO: Eliminate Win32 dependency
            Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
            if (regKey != null && regKey.GetValue("Content Type") != null)
                mimeType = regKey.GetValue("Content Type").ToString();
            return mimeType;
        }

Maybe we can use https://github.com/hey-red/Mime

Implement Adequate Command Line Parser

Maybe one of those:

FileSync create file
FileSync read file
FileSync update file
FileSync delete file

FileSync create dir
FileSync read dir
FileSync update dir
FileSync delete dir

-s | --serviceaccount
-c | --certfile

-n | --name
-g | --grantpermission
-p | --localpath

Add Better Documentation

Implement Logging

As this toll will run unattended there should be some logging.

Migrate to netcoreapp2.0

• Migrate to netcoreapp2.0
• Update NuGet packages

Pass Metadata in Body When Creating a GoogleDrive File

In order to get #4 implemented at least the creation and modification time must be set, otherwise it seems to be empty in DriveApi.cs method UploadFile:

File body = new File();
body.Name = System.IO.Path.GetFileName(_uploadFile);
body.Description = "File uploaded by FileSync";
body.MimeType = GetMimeType(_uploadFile);
body.Parents = new List<string> { _parent };
body.WritersCanShare = true;

Add Housekeeping Features

Files with a certain file age should be deleted.

Jaxx.FileSync.exe [global] delete agedfiles -a | --age [30] -f | --folder [foldername]

• #6 must be solved before this can take place

Taking the current timestamp and delete back for x days won't be good if a backup haven't run for y days without being noticed - this could probably mean loss of backups.

• For better backup strategy maybe the last x files should be kept while all older ones were deleted.
• Or we look at the latest modified days to determine the "agedfiles" and go back from their instead of taking the current time.
