When you start an on-demand backup of a virtual machine (VM), the backup operation begins
immediately without waiting for a schedule to run.
About this task
Typically, the VMs in your VMware datacenter are backed up when a schedule is run. However,
you might want to start an on-demand backup if you notice that a VM was not backed up recently or if
a backup completed with errors. You can also start an on-demand backup of a VM that is excluded from
scheduled backup services. Tip: Any retention policy settings are observed during an
on-demand backup. The retention policy for a VM determines how many backup versions of a VM can
exist on the
IBM Storage Protect server. Depending on how many
backup versions of a VM can exist on the server, running an on-demand backup of a VM might cause
older backups to expire. When backup versions expire on the server, they are removed from server
storage. For example, if a VM was backed up four times, and only four backup versions can exist on
the server, running an on-demand backup causes the oldest backup version to expire.
To check the number of backup versions that can exist on the server, select a VM in
the vSphere Web Client and complete one of the following actions:
- VMware vSphere 6.0 or earlier: Click .
- VMware vSphere 6.5 or later: Click .
You can back up an existing VM by selecting the VM in the vSphere Web Client
object inventory and using the Actions menu. You can also view and back up an
existing VM from the object that contains the VM, such as a datacenter, resource pool, host, or host
cluster.
Procedure
To start an on-demand backup of a VM, complete the following steps:
-
Select a VM in the vSphere Web Client object navigator and click .
You can also select an inventory object that contains the VM or VMs that you want
to back up and click . Complete one of the following actions:
- Right-click one or more VMs, and click Backup.
- Select one or more VMs, and click the Backup icon.
- Select one or more VMs, and click Backup in the
Actions menu.
-
Complete the following fields in the Back Up Virtual Machine
window:
| Option |
Description |
| Server backup type |
Select the type of backup to run:
- Incremental
- Backs up the blocks that changed since the previous backup (full or incremental). The most
recent incremental is appended to the previous backup. If a full backup does not exist for this VM,
a full backup is automatically performed. As a result, you do not have to verify that a full backup
exists.
- Full
- Creates an image of an entire VM. After the full backup is taken, there is no requirement to
schedule additional full backups. When full is selected, VM templates that are unchanged since the
last backup are also included.
|
| Data mover |
Select the data mover that you want to use to move data to the backup location.
Typically, you can accept the default data mover. However, to improve workload balancing in some
situations, you might select a data mover that is not heavily used.
If there is a data mover assigned to the VM, that data mover is the
default. If a data mover is not assigned to the VM or the assigned data mover is no longer valid,
the first data mover in the list of data movers that are available for the VM is the default.
Available data movers are listed in alphabetical order.
Do not select a data mover that is
currently in use for a backup or restore operation
|
| Backup destination |
Select the destination for the virtual machine backup. Depending on the location of the
virtual machine, you can back up to the IBM Storage Protect
server, to the local hardware storage, or to both locations.
|
| Disk protection |
Select the virtual machine disks to include in backups. The disks are identified by the disk
numbers. Custom disk selections are available if the Disk Backup List
(IBM Storage Protect) category and tag values are set. See Supported data protection tags.
|
| Data consistency |
Select the type of snapshot and retry attempts that are used for backup:
- Always application consistent
- Attempts two file system and Microsoft Windows VSS quiesced snapshots before failing the backup.
- Attempt application consistent
- Attempts two quiesced snapshots and, as a final attempt, a nonquiesced, crash-consistent
snapshot.
- Machine consistent only
- Attempts only a nonquiesced snapshot for VMs that can never complete a quiesced snapshot.
|
| Application protection |
If a single VM is selected, select Enabled to allow applications such as Microsoft
SQL Server and Exchange Server to truncate logs and commit transactions before the backup operation
begins. This enables the application to resume from a consistent state when the backup
completes. Select Keep Microsoft SQL Server logs if applicable if you do not want the logs
to be truncated.
If a multiple VMs are selected, choose Current value to use the value
that is currently set for each virtual machine or select Disabled to disable application
protection for all selected virtual machines.

progress of the backup operation.
To see backup tasks, you might have to make sure that tasks for all users are shown. For more
information about viewing tasks for all users, refer to the documentation for the version of VMware
vSphere that you are using.
Results
After the backup operation is completed, select an inventory object that contains the VM and
click to view the backup information for the VM.
