Unstructured data — images, video, logs, documents, and media files — is growing fast as digital business expands, pushing data volumes from terabytes into petabytes. Enterprise storage is also diversifying, moving from traditional file storage to object storage and, increasingly, to multi-cloud and multi-data-center architectures.

Object storage has become a preferred choice for hosting massive volumes of unstructured data, thanks to its scalability and cost efficiency. But as adoption deepens, new management challenges follow, especially when enterprises upgrade storage architecture, migrate to the cloud, consolidate data, or archive historical records:

  • Scale: Petabyte-level volumes and huge numbers of small files raise the bar for migration efficiency; traditional replication struggles with data scanning, difference detection, and consistency checks at this scale
  • Complexity: Public cloud, private object storage, and S3-compatible platforms often coexist, so cross-platform migration must handle both compatibility and consistency
  • Growth: Continued data growth is pushing enterprises toward archiving and tiered storage to use resources more efficiently

i2dto efficient object storage data migration and synchronization

i2DTO: Sync and Migration for Object Storage

To address these needs, Info2soft has launched i2DTO, an object storage management platform built for migration, synchronization, and archiving. i2DTO synchronizes and recovers data between local or NAS storage and object storage, and replicates data between different object storage platforms.

Broad platform compatibility

Enterprises often run several object storage platforms side by side. i2DTO supports:

  • AWS S3
  • Alibaba Cloud OSS
  • Tencent Cloud COS
  • Huawei Cloud OBS
  • Ceph
  • A range of S3-compatible platforms

This enables migration across heterogeneous storage environments.

Multiple comparison mechanisms for consistency

Data consistency is a top concern in large-scale migration. i2DTO ensures accuracy through:

  • Scanning and comparing source and target data to identify new or changed content
  • Syncing only the differences to the target
  • Verifying consistency using file size, MD5 checksums, and intelligent object comparison

Multi-channel parallel and incremental sync

For petabyte-scale migrations and large volumes of small files, i2DTO combines:

  • Multiple sync hosts running in parallel
  • Incremental sync (transferring only new or changed data)
  • Concurrent transfer, compression, and encryption
  • Bandwidth control

Together, these reduce redundant traffic, ease network load, and shorten migration windows for both ongoing sync and large one-time migrations.

Archiving and retrieval for optimized storage

To relieve pressure on local storage and support long-term retention, i2DTO can:

  • Move qualifying data to object storage based on defined archive conditions
  • Enable tiered management between production and object storage
  • Retrieve archived data on demand when business needs require it

Version history for full traceability

For synchronization workflows, i2DTO integrates with Elasticsearch to maintain a version history of synced files. If a file changes or a prior state needs to be restored, the corresponding version can be located and recovered — supporting data traceability and audit requirements.

i2DTO in Practice Across Industries

Object storage use cases are expanding beyond basic storage into backup, remote synchronization, migration, and long-term archiving. i2DTO is already deployed across industries including telecommunications and financial services.

Telecommunications: Scheduled Object Storage Backup

Item Details
Challenge A major telecommunications company had accumulated large volumes of unstructured business data on object storage and needed a more efficient backup approach as data continued to grow
Solution Scheduled full backups with protection policies set by data priority
Key mechanisms Priority backup for critical data, scheduled jobs, incremental sync, multi‑channel parallel transfer
Outcome Improved backup efficiency while maintaining data integrity and availability

Financial Services: Cross-Region COS Synchronization

Item Details
Challenge A major state-owned bank needed to strengthen object storage data security through cross-region protection
Solution Automatic backup from Tencent Cloud COS in Beijing to COS in Shanghai
Key mechanisms Geographic redundancy, automated synchronization
Outcome Reliable data support for business recovery in the event of a regional outage

Financial Services: Billion-File Migration Across Platforms

Item Details
Challenge A financial institution needed to migrate close to a petabyte of historical data from COS object storage to a private object storage cluster as part of a broader storage upgrade
Scale Nearly a petabyte of data across more than a billion file objects
Solution Workload split by bucket and path across multiple sync hosts running in parallel
Outcome Completed large‑scale migration with a smooth transition to the new platform

As object storage takes on a growing share of enterprise data, the ability to move and manage that data efficiently — across platforms, at scale, and without disruption — becomes a core requirement. i2DTO gives enterprises that capability today, with room to scale as storage environments evolve.
