摘要： Improved backup and storage operations are disclosed for virtual computing environments using a backup proxy server to perform storage operations on one or more virtual machine disks. The proxy server can include a module that intercepts application programming interface (API) calls, for writing backup data to a first location, prior to the data arriving on the proxy disk. During the intercept process, the data can be compressed in memory pages of the proxy server and redirected to an alternative backup disk location. The proxy server can also include a differential engine that identifies changes to the virtual machine disk at the block level since the last full backup. The differential engine can advantageously leverage memory pages of the proxy server to compare differences between signatures of blocks of the last full backup with signatures of new blocks. Subsequently, only blocks with non-matching signatures are processed for backup.

摘要： Backup systems and methods are disclosed for a virtual computing environment. Certain examples include a system having a backup management server that communicates with a host server having at least one virtual machine. The management server coordinates with the host server to perform backup copies of entire virtual machine disks from outside the guest operating system of the virtual machine. In certain examples, such backup systems further utilize a volume shadow copy service executing on the host server to quiesce virtual machine applications to put data in a consistent state to be backed up. The backup system then utilizes hypervisor snapshot capabilities of the host server to record intended changes to the virtual machine disk files while such files are being copied (e.g., backed up) by the host server. Such recorded changes can be later committed to the virtual machine disk files once the backup operation has completed.

摘要： Hybrid replication systems and methods for a virtual computing environment utilize snapshot rotation and differential replication. During snapshot rotation, data modifications intended for a source virtual machine disk (VMDK) are captured by a primary snapshot. Once a particular criterion is satisfied, the data modifications are redirected to a secondary snapshot while the primary snapshot is committed to both source and target VMDKs. The secondary snapshot is then promoted to primary, and a new secondary snapshot is created with writes redirected thereto. If the VMDKs become out-of-sync, disclosed systems can automatically perform a differential scan of the source data and send only the required changes to the target server. Once the two data sets are synchronized, snapshot replication can begin at the previously configured intervals. Certain systems further provide for planned failover copy operations and/or account for migration of a virtual machine during the copying of multiple VMDKs.

摘要： Virtual machine optimization and/or storage reclamation solutions are disclosed that manage virtual machine sprawl and/or growing enterprise storage costs. For instance, certain solutions receive recommendations based on one or more rules, policies and/or user preferences that identify storage and/or alignment criteria for virtual machine disk (VMDK) partition(s). In certain examples, a resize tool that operates within a host operating system of a host server dynamically resizes and/or aligns one or more VMDK partitions of a powered-down virtual machine. For instance, the resize tool can be injected to the host server from a remote management server and can resize and/or align the VMDK partitions without requiring contents of the VMDK to be copied to another VMDK. By reallocating storage and/or aligning the VMDK partitions, embodiments of the invention can increase virtual machine performance and improve storage management.
