In one embodiment, a computer-implemented method for server migration includes the step of, with an agent running inside a server, capturing a server image of the server, wherein the server image is independent of a source-compute infrastructure. The method includes the step of transferring the server image to a dedupe store. The method includes the step of transforming the dedupe stream of the server image into a bootable server image on a target compute infrastructure. The method includes the step of generating a recovery set of disks on the target compute infrastructure. The method includes the step of creating a recover-process server on the target compute infrastructure using a recovery set of disks.

Method and system of universal server migration

In one embodiment, a computer-implemented method of implementing a dedupe file system with constant ingestion and retrieval times for objects in dedupe file system achieved by synchronizing a garbage collection (GC) thread and reader (restore), writer (backup) threads in a dedupe file system includes generating, with at least one processor, a state machine for dedupe file system that coordinates concurrent data ingestion due to writers and data deletion due to garbage collector. The state machine has three states. 'Dormant' state when the GC thread is inactive and all writers freely ingest data into dedupe file system without any need for synchronization with GC. 'Data gathering' state when the GC thread determines the dedupe chunks for deletion in a garbage list and writers check for data chunks in the garbage list and filters out processed data.

In one embodiment, a computer-implemented method for server migration includes the step of providing an onsite system that comprises a server. A storage appliance is provided. The storage appliance is coupled with the onsite system. A bootable server image is created. The bootable server image is stored on the storage appliance.

Another step includes providing an onsite-dedupe storage node, wherein the onsite dedupe node initiates a replication operation, wherein the replication operation comprises the onsite dedupe storage node operation pushing or fetching a dedupe-image data from the one or more replication-site dedupe storage nodes. The replication from local dedupe storage node to remote dedupe storage node pushes data not present at remote. The replication from remote dedupe storage node to local dedupe storage node fetches data not present at local.

Methods and systems of a dedupe storage network for image management

In the dedupe storage network priority to data replication needs to be given over the garbage collection (GC) activity. For this purpose GC running on any site should not impose any locking on its peer sites for replication. For replication activity GC activity must be completely transparent. In the dedupe storage network, the retention policy of a replicated image is controlled by the site where the image was originated. Distributed GC running on the originating site can only inform the replication sites the list of expired replicated images and cleanup of replicated garbage chunks from its remote FS database for corresponding replication sites. But it cannot cleanup garbage chunks from replication sites. Garbage chunks can only be cleaned by the local GC running on that site.

In one embodiment, a computer-implemented method includes the step of accessing a set of data blocks in a local application server disk in an application server. It is determined which of the set of data blocks are used to store data. The data blocks used to store data are read to a deduplication store on the storage appliance. It is determined that a modification occurs to a data block in the local application server disk of the application server. The modification is read to the deduplication store. A remote virtual image of the application server can be generated from the deduplication store.

One-click backup in a cloud-based disaster recovery system

Various systems and methods can be used to perform backup to tape. For example, one method involves detecting an amount of storage in a tape drive that is available for concurrent access. The method then compares the size of a plurality of backup images to the amount of storage prior to initiating an archive operation. The method then involves adding information identifying a backup image to a list of backup images to be included in an archive operation and performing the archive operation, which involves writing the backup images to tape drive.
