Archiving data for long-term retention is a common use for cloud storage, Cloud archive involves tiering old data to the cold storage tiers of a cloud provider for long-term retention. Cloud archive offers the best of both with a cheaper price point than any on-premises disk solution and far better accessibility than tape. Cost-wise, AWS’ recently launched Deep Glacier Tier is priced at $0.0099 per gig per month, which adds up to about $12 per TB per year—far less expensive than just the hardware and software for any on-premises disk storage. From a data recovery standpoint, recalling data can be simplified to make data easily accessible for end users without requiring labor intensive workflows or error-prone processes, as required by solutions relying on tape.
The Cloud storage tiering was implemented with tiered storage file system filter driver. A file system filter driver intercepts requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request. File system filtering services are available through the filter manager in Windows. The EaseTag tiered storage filter driver can intercept the file I/O to the local storage and redirect it to the remote cloud storage by implementing the file system filtering functionalities which was provided by the Filter Manager framework.
Hierarchical storage management
EaseTag Cloud Storage Connect is a data storage technique which automatically moves data between high-cost local disk and low-cost remote cloud storage. EaseTag Cloud Storage Connect can help simplify the migration process by providing the transparent file access from the remote storage. Using the cloud as a storage tier, data can first be moved to a ‘warm’ archive tier of higher-performance disk, where it can still be accessed quickly to meet RPO and RTO SLA’s. As you retain archives for longer, older data can then be moved to a ‘cold’ archive tier with better economics. (This is similar to the tiered storage cost/performance model offered by Amazon S3 with its “warm” Standard tier, “cold” Infrequent Access tier and “frozen” Glacier tier.)
Integrate your exiting on-premises applications with remote cloud storage transparently
Our EaseTag Cloud Storage Connect service can connect an on-premise software appliance with cloud-based storage to integrate your existing on-premises applications with the remote cloud storage infrastructure in a seamless, secure, and transparent fashion.There are no interruption to migrate your on-premise files to the remote cloud storage, don’t need to change your existing applications and infrastructure.
- Set up file cloud migration policies based on the file type, file size, file attributes.
- Create stub file based on the policies after the file was migrated to the cloud storage, it can free up the space from on-premise storage.
- Transparent the cloud storage access by reading the stub file for your local application.
- Transparent moving data back from remote cloud storage to the local, re-hydrate the stub file for the recent access file based on the policies.
Data migration and create stub files
After the files were transferred to the cloud data center, then make these files to stub files ( see Figure 5). The stub file only take 4k physical space, and the file size didn’t change, compare the Figure 2 and Figure 4, it shows that the volume gains 110 GB free space back, that’s because the original physical files data space were released. The stub files have the offline icon which will let the backup software and anti-virus software don’t read these files.

Access stub files or restore files
When the user application access the stub files, the EaseTag tiered storage SDK can read back a block of data of the file, this method is especially good to the large file, it is much faster than restore back the whole file. For example, the application only wants to read back 64kb data in offset 0 for a file size is 100GB, it will only return the 64Kb data. For some applications, they need to read the whole file, the SDK also can restore the whole file in the first read.
