A Perl client for Office 365 services like OneDrive Personal or OneDrive for Business.

# authenticate
onedrive.pl -a [-v] /path/to/destination

# synchronize
onedrive.pl -s [-c] [-v] [-C|-D|-K] /path/to/destination

# logout
onedrive.pl -x /path/to/destination

OneDrive-Perl is a backup client for Office 365 services like OneDrive Personal or OneDrive for Business, i.e. a program that mirrors all the changes on your cloud service to a local machine, using the Graph API and obviously written in Perl. It is allowed to crash, but not to lose a single operation. It is a backup client, so it has no write permissions and doesn't perform a two-way synchronization.

OneDrive-Perl needs Perl 5.24.0 or higher. It is recommended to use a Perlbrew environment. After you have installed perlbrew, type as user:

perlbrew install 5.30.1
perlbrew switch 5.30.1

Next you need the most recent versions of the following Perl modules:

• Data::Dump
• Data::ICal
• Digest::QuickXor
• IO::Socket::SSL
• Mojolicious
• Mojo::File::Role::Digest
• Mojo::SQLite
• Print::Colored
• Text::CSV_XS

Don't use the outdated packages included in your distribution, instead install them from CPAN with

cpanm --installdeps .

IO::Socket::SSL depends on the SSL development libraries. On Debian they are called libssl-dev.

Now you can install OneDrive-Perl.

git clone https://github.com/Tekki/onedrive-perl.git

Update the code with

cd path/to/onedrive-perl
git pull

In the following, onedrive.pl refers to the full path to the onedrive script, for example

~/git/onedrive-perl/script/onedrive.pl

destination[s] is the path where the content of your library will be copied to, for example

onedrive.pl OPTIONS ~/onedrive/personal

You can call it on multiple destinations

onedrive.pl OPTIONS ~/onedrive/personal ~/onedrive/shared_a ~/onedrive/shared_b

It has the following subdirectories:

destination
|-- .config
|-- calendars
|-- contacts
|-- documents

.config is used to store internal data, contacts to backup the contacts, and documents is the place where the files from OneDrive will be downloaded. The calendar events are copied to subfolders of calendars.

If the destination doesn't exist, the directory tree is created as necessary.

onedrive.pl -a destination[s]
onedrive.pl --authenticate destination[s]

This will display a link like

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=...

that you have to open in your browser. Log in with your Microsoft account and allow the application to access your Office 365 instance. You will be redirected to a blank page on microsoftonline.com. Copy the resulting URL from your browser back to

Paste the response URL:

and press ENTER. If the authentication is successful, you can choose which drive you want to synchronize and give it a description.

On OneDrive Personal, you get a dialog like the following:

1: Tekki / OneDrive Personal
2: Bonnie Parker / Shared with Tekki
Select drive [1]:
Description [Tekki / OneDrive Personal]:

To keep the proposed values, simply press ENTER.

If you are logged in with a business account, you are asked to provide a SharePoint URL.

To backup a SharePoint drive, enter the main URL of the site.
SharePoint URL []:

The main URL starts with your_company.sharepoint.com and ends with SitePages/Homepage.aspx. If you don't enter a URL, a connection to your OneDrive for Business will be made, otherwise you can choose between the drives of your SharePoint site.

1: Contoso / Teamwebsite Documents
2: Contoso / Teamwebsite ...
...
Select drive [1]:

onedrive.pl -s destination[s]
onedrive.pl --synchronize destination[s]

This will synchronize your OneDrive with the destination and (hopefully) exit without a message. If you want to see some information about what the program is doing, use one of

onedrive.pl -s -v destination[s]
onedrive.pl --synchronize --verbose destination[s]

You can limit the synchronization to a specified area with

onedrive-pl -s -C destination[s]
onedrive-pl --synchronize --calendars-only destination[s]

onedrive-pl -s -D destination[s]
onedrive-pl --synchronize --documents-only destination[s]

onedrive-pl -s -K destination[s]
onedrive-pl --synchronize --contacts-only destination[s]

To display the number of pending tasks write

onedrive-pl -c destination[s]

Crashes: At this moment, the program will crash maybe once a day, especially if errors on the side of Microsoft occur. As it develops, these crashes will be less frequent. But even now you should be able to restart it without creating a single inconsistency.

onedrive.pl -x destination[s]
onedrive.pl --logout destination[s]

This disconnects the destination from your OneDrive, but keeps the details of the connection and the database of the documents. You can authenticate again any time. To revoke all the rights you gave to this program, go to your Personal Microsoft Account or to your Office 365 Business Account and delete it from the list.
