Frequently Asked Questions

BluSync for Sync, Share & Collaboration

1. Can we sync On-premises File server data over cloud? 

Yes.  BluSync for Secure File Services is designed specifically for this.  Parablu provides services to do a one-time migration of your on-premise file server data to the cloud and allows your users to access that data from the endpoint seamlessly no matter where they are working from. 

2. What is supported storage?

We’re a storage agnostic solution and can work with a wide variety of storage targets.  We support the major cloud providers such as AWS S3, MS Azure Blob storage, GCP object storage, IBM Softlayer, etc.  We also support on-premise disk storage sub-systems.  We can also work with cloud storage subscriptions you have such as OneDrive for Business or Google Drive. 

3. Does automatic syncing preserve user rights in cloud setup? 

While we can allow/disallow access to files at a user level, the granular ACL level permissions you may have on your on-premise file systems cannot be carried over.  You can however give each user their own insulated space for their data, and also have shared folder/sub-folder structures where groups of users have equal privileges to access files. 

4. Is there a way to provide specific folder access to End-user? 

Yes. Absolutely.  By default, each user would get access to their own folder to keep their private data.  But it is also possible to identify any folder for specific access to only a single user. 

5. Can we restrict the user rights to access the data? 

Yes.  You can choose to allow someone only the ability to read data, but not download or share the data as an example. 

6. Can we allow users just to view the file without downloading it to the system? 

This is supported for many popular file types – such as office documents, PDFs, etc. – but not all possible file types.

7. Can I share a single file with the external user?

Yes.  BluSync for Secure File Sharing is designed specifically for this.  Sharing a file is as simple as having a user right-click on a file to share it, and provide an email address to send a secure link to.  It is of course possible to secure the sharing action by protecting the link with a complex password, enabling multi-factor authentication, specifying IRM rules (no-download, etc.), and even specifying an expiration date for the shared URL. 

8. Can I share a folder with an external user? 

Yes.  BluSync for Secure Collaboration is designed for this.  Sharing a folder is done via a concept called a mini-cloud.  Think of it as a shared folder area with multiple memberships.  To share a folder with an external user, just create a username in BluSync for the external user, create a mini-cloud and make the external user a member of the mini-cloud along with yourself.  Whatever data you populate in the shared folder (mini-cloud) will be automatically made available to the external user as well. 

9. Can I download multiple folders at the same time? 

Yes, while a folder download is in progress, may switch to another tab and initiate the download of a separate folder.

10. Can I synchronize the data to my endpoint machine using an agent? 

Absolutely.  BluSync comes with an endpoint agent on both Windows and Mac.  The agent is designed to keep the data on the user endpoint in sync with the cloud copy without forcing the user to have to upload or download files manually via a web browser. 

11. Is there any option to auto-delete the files which I uploaded? 

Yes.  It is possible to enable a policy setting that lets you determine how long uploaded files should be preserved.  If you’d like to remove files 30day after upload or 365 days after uploading, for instance, you can enable that to happen automatically. 

12. Can multiple users use the same files at the same time? 

At this point, there is no provision to open and edit the files directly in BluSync.  Users can however download the files to their endpoint and use desktop applications to edit and create content.   

13. If I upload the file after the modification, will the application create a new copy of the file? 

A new version of the file is created. 

14. What are the available security options for secure file sharing? 

There are several.   

Password protection is the most basic.  If the shared file is protected by a password, the recipient is challenged for it when they click on the URL to access the file.  It is also possible to enforce a complex password.   

Next, it is a password to enable multi-factor authentication.  In this case, the recipient would not only have to key in the password, they’d also have to specify a one-time secret that is sent to their Microsoft or Google Authenticator app on their phone. 

The user can also specify how long the shared link is allowed to be valid – like 1 day or 1 week.  Once that time expires the link self-destructs and will not let anyone access the file even if they key in the right password. 

Lastly, it is possible to restrict the recipient’s access to the file – the sender can choose to let the recipient only view the data in a web browser, but disallow save/print/download, etc. 

15. Can the administrator allow file sharing only by a specific group of users? 

Yes.  This is easily controlled via policies.  File-sharing can be allowed disallowed at a policy level.  So, to allow file sharing by a specific group of users, just add them to a single policy and enable file sharing just in that policy. 

16. Do you audit logs End-user and Administrator activities?

Yes.  All key activities are fully audit logged with details of the actions taken.  Audit logs can be downloaded for review at any time and can be filtered by user, time period, etc. 

17. Does the Administrator have an option to view shared file details by the user? 

Via the audit logs – Yes.  They may not be able to view the actual file, but all the sharing details will be audit-logged. 

18. Can guest users get access to a Shared folder for x number of days? 

Yes.  Mini-Clouds (shared folders) can be configured to expire/disable after a given time period. 

19. Can we block the guest user account automatically after x days? 

User IDs can be created to auto-expire after a set number of days. 

20. Can multiple users collaborate on a single project? If yes, then How it is configured? 

Yes. BluSync for Secure Collaboration is designed specifically for this.  This is accomplished using Mini-Clouds – the shared folder feature that is built into BluSyncTo allow a set of users to collaborate, create a shared folder (or a MiniCloud) and make all collaborators a member of the mini-cloud.  Whatever data any of the users populate in the shared folder (mini-cloud) will be automatically made available to all the other users as well. 

21. Can we allow Shared folder access to a specific set of users? 

Yes – see the answer above. 

22. Can we make the Project manager the owner of a Minicloud? What operations Minicloud Owner can perform? 

Yes.  You can create a mini-cloud, add a project manager to the mini-cloud and make them a mini-cloud Administrator.  From this point on, the mini-cloud administrator can manage the mini-cloud – they can add or delete other users as they deem fit. 

23. Is there any alert to notify Minicloud owner about data upload?

It is possible to a periodic, auto-emailed report that informs an administrator of all activity that occurs in a mini-cloud.  Uploads, downloads, sharing, deletions, new user additions, etc. 

24. Can the Administrator Revoke End-user access from a specific mini cloud after the project is closed? 

Yes. Absolutely.  Individual end-users can be removed from the mini-cloud as the administrator sees fit.  The entire mini-cloud can also be disabled once the project is complete. 

25. Does Parablu has the capability to block malicious file upload?

Yes.  This is a built-in feature but separately licensed.  Enabling this will result in all file uploads (whether via a web browser or the agent sync) being automatically scanned for malware.  Files that are scanned as being positive for malware will be disallowed from being uploaded and the attempt will be logged in the activity log. 

26. Is there a way to know if any malicious file has been uploaded in the system? 

The activity log will inform the administrator of any malicious file upload attempts.  However, it is quite possible that the anti-malware scanning is unable to catch all malicious files.  It is always advisable to have several layers of security defense and not depend entirely on the BluSync malware scanning capability. 

27. Can Parablu encrypt the data before sharing? 

Yes, as a matter of fact – this is always done.  Remember that when files are shared, BluSync only shares a URL link via email – never the actual file.  When a recipient clicks on that link and authenticates is when the file becomes accessible to them.  Even then, the file is transferred over an encrypted channel to the recipient and is decrypted only after it reaches their endpoint system.
