  • 1. Why do I need a separate archive solution for Microsoft Office 365?

    Having a separate and centrally accessible archive for Microsoft 365 emails and OneDrive data can provide additional protection for critical data while optimizing the cost of data retention. Specifically, here are a few reasons:

    1. Move data assets used by former employees to Vaultastic to optimize subscription costs.
    2. Regulations, laws, and IT best practices need a separate and independent backup from where the data is generated.
    3. A large cloud mailbox does not protect data from accidental or intentional deletions.
    4. Exchange Online Archive only extends your Inbox size and is not a complete copy of your data and, hence, not a data protection tool.
    5. Switching on the legal hold option prevents the user from deleting data henceforth, but it cannot undo earlier deletions.
    6. This multi-cloud strategy reduces your risk of vendor lock-in as you control your most critical data in an independent infrastructure.

  • 2. I am currently using Microsoft 365 with sufficient storage. Do I still need a separate data archive?

    Having adequate storage in the active user mailbox or OneDrive may not protect your critical data against accidental or intentional erasure, theft, or corruption.

    In addition, Microsoft 365 offers Exchange Online archiving capabilities to extend the size of the Inbox. Coupled with features such as legal hold and retaining deleted items for some time, it may seem as if the data is protected.

    However, it may not provide a complete, up-to-date copy of all the data and the granularity, searchability, and compliance capabilities that a separate data archive solution offers.

    If your organization has specific regulatory or legal requirements for data retention and archiving, or if you need advanced search and discovery capabilities for historical data across user vaults, it may be beneficial to use a separate data archive solution for Microsoft 365. Learn more here

  • 11. What are the pros and cons if I back up my files from OneDrive to an external hard drive?

    If you are doing this to keep a copy of all your files on OneDrive, consider a safer, more secure, and scalable option like Vaultastic. A OneDrive backup to an external hard drive increases data loss, corruption, and tampering risks, rendering the whole solution very risky

  • 13. What is the process for archiving files from OneDrive for Business?

    Archiving files from OneDrive for Business involves creating a backup copy of the files to separate independent storage on another cloud.

    Vaultastic does this by allowing you to define the files you should archive from the user’s drive based on the date and time and other relevant attributes of the files.

    Using the same tools, you can also take regular incremental backups of the files changed between the two backups.

  • 14. How often should I archive files from OneDrive for Business?

    The frequency of archiving files from OneDrive for Business will depend on your organization's specific needs and regulations.

    Since the files on OneDrive for Business carry business-critical data generated by users, we recommend a frequent schedule of incremental backups after the entire initial backup.


    A daily backup works best.

  • 18. Since OneDrive is on the cloud, how does another cloud backup for OneDrive help?

    Even though OneDrive is on the cloud, it is not safe from the tampering of files or accidental and intentional file erasures.

    Also, when an employee leaves your organization, how will you preserve the corporate data generated, stored, and used by the employee via OneDrive?

    In a regulated industry, you must have an independent backup of all data in separate, safe, secure, and durable storage.

    Hence, regularly backing up all your business-critical data on OneDrive to different cloud storage is advised.

  • 1. My company is not part of a regulated industry. Do I still need to archive email?

    The rapid digitization of organizations across industries is driving reliance on modern tools for business communication. 

    And email has become a dominant form of communication between organizations and their customers and partners.

    This shift creates large volumes of unstructured business communication data, making recovery of data complex while handling data loss, theft, or corruption cases.

    And the growing sophistication and number of cyberattacks are not helping to manage data-related risks.

    A secure, immutable, central archive can help you preserve email data in tamper-proof vaults for extended periods and ensure that the data is online, search-ready, and discoverable on demand.

  • 2. I use a cloud email service like Google Workspace/MS365, which gives me 30/50GB of storage per user. Why do I still need to archive email when my cloud mailbox storage is sufficient?

    Your end-users typically manage your cloud mailboxes and have full rights to delete and move emails. 

    Hence you are never sure if the mailboxes have all the emails the users ever sent or received. 

    Thus an inability to retrieve any data requested by the auditor or compliance officer can put your organization at a significant legal or compliance risk.

    Besides, you also run the risk of IP theft or data loss, which can financially cost your organization.

    As a data management best practice, having an independent, immutable archive of all your data will substantially de-risk your organization and improve your ability to respond to data access requests.

  • 1. How does this Email Storage solution help me stay within my purchased mailbox limits of 30GB or 50GB?

    Now it’s safe to delete emails from your active mailboxes since you will find them on Vaultastic.

  • 3. I practice periodically downloading old mail from my users’ mailboxes to PST files and storing them offline, which works for me. Why should I adopt Vaultastic as an Email Storage Management solution?

    These traditional methods are limiting:

    Manual process leading to low productivity: 

    Your IT Team, currently engaged in this work, can be doing something which adds more value to your business.

    Risk of Data loss:

    Since your capture is periodic, you will likely miss any added and deleted emails in the gap. Also, the human element and traditional storage devices fragment data and open it to tampering, theft, and loss.

    Difficult to find information:

    The fragmented, raw data makes it challenging to locate specific information quickly and accurately when requested during litigation or audits.

    Vaultastic’s data storage management tools address the above and more challenges faced in data storage and data management. Learn more
