Choosing a vss provider (microsoft hyper-v server 2012 r2 and earlier) – veeam backup guide for hyper-v

Before you configure backup jobs, it is recommended that you decide what VSS provider will be used to create and maintain volume shadow copies.

By default, Veeam Backup & Replication automatically selects a VSS provider on every volume. Data recovery center Every 4 hours it rescans all Microsoft Hyper‑V hosts added to the backup infrastructure and updates information about connected volumes.

Database entry Veeam Backup & Replication also collects information about software and hardware VSS providers available on every volume.

If hardware providers are available, Veeam Backup & Replication selects a hardware provider to create volume shadow copies on a volume. Database options If no hardware providers are installed, Veeam Backup & Replication selects the VSS system software provider. Database jokes If necessary, however, you can assign a VSS provider on every volume manually.

If both software and hardware providers are available for a volume, it is recommended that you select a hardware provider. R studio data recovery download crack Although software providers are generally applicable to a wider range of storage platforms, they have a number of limitations:

• By default, jobs working with the same volume can take up to 4 snapshots of a volume simultaneously. Database software for mac If necessary, the number of snapshots can be increased.

• Hardware providers operate at the storage system controller level. Database questions for interview Software providers operate at the software level, between the file system and the volume manager, and can cause a significant performance overhead on the source host.

• [For Microsoft Windows Server 2008 R2] Hardware providers can work with several snapshots simultaneously. Database cleaner That is, if you have several jobs that work with the same volume, you can run them in parallel. Data recovery hard disk If you use a software provider, Veeam Backup & Replication serializes VM processing. Data recovery jakarta You will not be able to start several jobs working with the same volume simultaneously. 7 data recovery suite registration code The volume on which VM disks reside remains locked by one job for the whole period of data processing. Data recovery raw After the job completes, the volume becomes accessible for other jobs.

• [For Microsoft Windows Server 2008 R2] Software providers are not suitable for backup on CSV’s — a significant backup window is required to back up VMs that reside on the same volume but are registered on different hosts. Database library When a cluster node initiates a snapshot on a CSV, the CSV is switched to the Backup in Progress, Redirected Access mode.

• If a hardware provider is used to take a snapshot in such case, the CSV stays in the redirected mode while the snapshot is taken. Data recovery ssd After a volume shadow copy is created, the CSV resumes direct I/O.

• If a software provider is used to take a snapshot, the CSV stays in the redirected mode until the backup process completes. Data recovery on iphone If large virtual disks are processed, backup time can be significant.
