![]() ![]() If you restore the volume store to the current VCH or add it to a new VCH, the configuration of the vic-machine -volume-store argument matches that of the path you backed up. This will copy the disks, the folders, and the metadata.īy backing up the root folder, you keep the path structure intact. However, as mentioned above, this does not work for all datastore types, and most probably results in fat versions of volume disks.įor example, you can use Veeam to create a File Copy Job that copies the /vmfs/volumes/iSCSI-nvme/volumes/my-vch-logs volume store from the example. File Copy ApproachĪ file copy approach is the simplest way to back up volumes, because you can back up an entire volume store by copying the root folder from the datastore. For example, it would potentially be a waste of bandwidth to back up ephemeral state or cached immutable image state. This is a good way to ensure that you have backed up everything, but it also makes it more important to use different datastores for different types of state. Your backup solution might have the ability to create snapshots or clones of entire datastores. The following examples show how you can use different approaches to back up the iSCSI and vSAN volume stores used in Example: Persistent Container State in the previous topic. You should experiment with the clone and backup solutions that you use to be aware of the consequences of making thin disks fat, particularly when it comes to the impact of restoring disks from a backup. For more information about vmkfstools, see Using vmkfstools below. The vmkfstools utility maintains the thinness of a volume disk when it makes a clone. For more information about the file copy approach to backup, see File Copy Approach below. Most file copy approaches to backup will make a byte-for-byte copy, which results in the creation of a fat clone of a thin disk. Note that some methods of cloning preserve thin provisioning and some do not. ![]() This means that they only take up as much space as they need on the datastore, up to a set capacity limit. VSphere Integrated Containers creates VMDK volumes as thin, lazy zeroed disks. For more information about cloning volumes, see Datastore Approach below. As such, currently the only way to back up volume disks is to clone them. This is by design, so that disks are not deleted when a container is deleted, but the disks are also not subject to snapshots. This can protect against corruption, hardware failure, and deletion.Ĭontainer VMs are not designed for snapshots to be taken, and volume disks are mounted as independent persistent disks. Snapshots can protect against data corruption, but they do not protect against datastore hardware failure or accidental deletion, unless you clone and move the snapshot.Ĭloning a VM or a disk performs a deep copy that you can move to a different datastore and bring back in its entirety. ![]() Taking a snapshot of a VM or disk allows its state to be frozen in time on the same datastore and potentially restored at a future date. Tools such as vmkfstools provide one way to ensure that a virtual disk is cloned properly. ![]() This is because in vSAN, virtual disk data is a hidden object, so only the metadata can be seen. Backup solutions have file-based backup and restore, but whether or not this is the correct approach depends on the characteristics of the datastore.įor example, tar and untar will work with virtual disks on a FreeNAS, ZFS, or iSCSI setup, but will not work with VMware vSAN. They might not allow you to back up virtual disks on their own. Most commercial backup solutions focus on making clones or snapshots of a VM. However, there are some important caveats to this.
