Low-Profile Source-side Deduplication for Virtual Machine Backup
نویسندگان
چکیده
This paper presents a source-side backup scheme with low-resource usage through collaborative deduplication and approximated lazy deletion when frequent virtual machine snapshot backup is required in a large-scale cloud cluster. The key ideas are to orchestrate multiround duplicate detection batches among machines in a partitioned asynchronous manner and remove most unreferenced content chunks with approximated snapshot deletion. This paper discusses the challenges, main design and strategies, and evaluation results.

Low-Cost Data Deduplication for Virtual Machine Backup in Cloud Storage
In a virtualized cloud cluster, frequent snapshot backup of virtual disks improves hosting reliability; however, it takes significant memory resource to detect and remove duplicated content blocks among snapshots. This paper presents a low-cost deduplication solution scalable for a large number of virtual machines. The key idea is to separate duplicate detection from the actual storage backup i...
متن کاملDEDISbench: A Benchmark for Deduplicated Storage Systems
Deduplication is widely accepted as an effective technique for eliminating duplicated data in backup and archival systems. Nowadays, deduplication is also becoming appealing in cloud computing, where large-scale virtualized storage infrastructures hold huge data volumes with a significant share of duplicated content. There have thus been several proposals for embedding deduplication in storage ...
متن کاملIZO: Applications of Large-Window Compression to Virtual Machine Management
The increased use of virtual machines in the enterprise environment presents an interesting new set of challenges for the administrators of today’s information systems. In addition to the management of the sheer volume of easily-created new data on physical machines, VMs themselves contain data that is important to the user of the virtual machine. Efficient storage, transmission, and backup of ...
متن کاملDEDIS: Exact Deduplication for Primary Distributed Storage∗
The removal of duplicate data from primary storage volumes in a cloud computing environment is increasingly desirable, as the resulting space savings contribute to the cost effectiveness of a large scale multi-tenant infrastructure. However, traditional archival and backup deduplication systems are not suited for large scale virtualized infrastructures and the I/O demanding applications there d...

I.INTRODUCTION In this paper with the potentially unlimited storage space offered by cloud providers, users tend to use a large amount space as they can and vendors continually look for techniques aimed to reduce redundant data and exploit space savings. A technique which has been widely adopted is crossuser deduplication. The simple idea behind deduplication is to accumulate duplicate data onl...
