petabytes of data
on-premise and in the cloud.

Tiger Bridge is certified by these cloud storage partners

Migration and Integration

Optimize and save – download Tiger Bridge today and reclaim your premium storage, use local and cloud data storage tiers, and restore only what you need.

It’s easy, try it now!

Tiger Bridge software-only solution does not require complex cloud storage gateway server or backup appliance. Tiger Bridge expands Windows NTFS file system capabilities with seamless tiering to cloud, NAS/DAS or tape. By optimizing data placement for frequent access, nearline and archive-ready files, Tiger Bridge preserves Active Directory ACLs and ensures data is stored in the right place, at the right time.

Tiger Bridge requires no downtime to deploy and no change to user experience, application or workflow configuration.

HSM Tiering & Synchronization

Tiger Bridge provides a simple administrative console where HSM policies are created to determine when files will be replicated and tiered based on last access time and/or volume capacity.
Managed volumes maintain local performance for active files while policies work in the background to replicate, migrate, and tier data between the local volume and cloud, DAS/NAS or tape for backup, archive, capacity management, disaster recovery, or cloud services.

Tiered files are replaced with zero-byte stub files in the NTFS file system so petabytes of data can be accessed even from a modest local volume. Stub- files are placeholders that allow applications to function normally, as if the data exists in its original location.

  • Provides users and applications with seamless access to data, regardless of where it is stored
Protects Data End-to-End
  • Preserves native Active Directory / ACLs
  • Eliminates intrusion points with direct server-to-cloud migration
  • Transfers data to/from cloud using SSL/TSL encryption
Reduces Storage Cost
  • Limits the amount of block storage required
  • Extends block storage across cloud storage classes (active and inactive)
  • Optimizes cloud data placement for frequent access or low cost archive
Enables Global Collaborative Workflows
  • Synchronizes specific folders or entire file systems
  • Keeps any number of servers and/or workstations in sync
  • Enables global updates of shared dataset
Helps Manage Petabytes of Data
  • Replicates new files and file updates to cloud automatically
  • Frees up space locally by turning inactive data into stub files
  • Retrieves data automatically from cloud when stub files are being accessed
Minimizes Recovery Time Objective (RTO)
  • Preserves and restores file attributes to/from the cloud
  • Restores file system tree-structure ”on-demand” for expedited operational recovery of huge datasets
  • Retrieves file content ”on-demand” with prioritized partial restore

  • Enables new and scalable collaborative workflows
  • Connects with cloud services for analytics, facial recognition, AI, ML, etc.
Expands Your Horizon
  • Stores your data in an accessible format – zero lock-in
  • Works with on-premises, hybrid and cloud-based workflows
  • Supports Cloud, Tape Libraries (LTFS) or DAS/NAS targets
Tiger Bridge extends a local file system into a target storage.
Figure 1 shows a regular server with local volume. Figure 2 shows how the local volume can be extended into another volume; an SMB share; a tape library or an object storage (i.e. cloud). Unlike with Tiger Pool where users can access any of the pool member directly, users ALWAYS access the local volume with Tiger Bridge. If the data is not available on the local volume, it is recalled. As such, Tiger Bridge can be used to create a high-speed SSD cache in front of traditional HDD RAID.

Figure 3 shows how Tiger Bridge can be used for Data Recovery applications where near-zero downtime is required. While in a standard backup-restore procedure ALL data would need to be restored for the recovery site to be operational. With Tiger Bridge, the recovery site only needs to read metadata to generate stub-files in order to resume operations. Files will get restored as they are accessed. Such an approach takes a fraction of the time of traditional restore.

Server Requirements

  • PC with 64-bit (x64) processor.

    Note: Tiger Bridge actively uses the APIs provided by the target provider (S3, DDN WOS, etc.). These APIs may take significant amount of CPU depending on connection and the amount of data moved. Please, refer to the minimum CPU requirements of your target provider.

  • 64-bit Microsoft Windows® 7/Server 2008 R2/Windows® 8/Server 2012/Server 2012 R2/Windows® 10/Server 2016.

  • 4 GB of physical RAM at least.

  • 30 MB of available hard-disk space for installation.

    Note: Tiger Bridge keeps track of the files it manages in a database, stored in the product installation folder. The size of the database grows proportionally to the number of files managed. For example, if Tiger Bridge manages 1 000 000 files, the size of the database is approximately 100MB. Unless there’s enough free space for the database, Tiger Bridge is unable
    to operate.

  • TCP ports 8536 and 8537 should not be blocked by a firewall if any.

Storage Requirements
Source Volume Requirements:
Tiger Bridge supports any already existing NTFS volume, mounted on the computer running Tiger Bridge as a local volume with Read & Write permissions.

Target Storage Requirements:

  • Microsoft Azure Blob Storage

  • Amazon S3 object storage

  • S3-compatible object storage (using protocol signature version 2)

  • Spectra BlackPearl Deep Storage Gateway

  • IBM Cloud Object Storage

  • Backblaze B2 Cloud Storage

  • Wasabi cloud storage

  • SMB/CIFS network share

  • another volume, mounted on the computer as a local volume with Read & Write permissions

  • tape library compatible with Microsoft Windows API, set up to operate in random mode (it does not automatically load tapes into the tape drives) or to automatically switch from sequential to
    random mode upon receiving SCSI commands for access from a media changer aware application.

    Tiger Bridge is currently verified to provide full functionality with the following tape library

    Quantum Scalar i3

    Qualstar Q24

    Qualstar Q80

    Tiger Bridge is currently verified to provide full functionality with the following tape drives:

    IBM Ultrium 6

    IBM Ultrium 7

    IBM Ultrium 8

    the tapes must be formatted using a proprietary LTFS format.
