You apply snapshot
schedules to storage cluster objects: VMs, VM folders, or resource pools.
If you re-register
the vCenter cluster, your HX Data Platform snapshot schedule is lost. If this
happens, reconfigure your snapshot schedule.
You can schedule a
snapshot to adjust your backup requirements. For example, you can retain more
frequent snapshots of critical data. If there is a disaster, you can restore
recent snapshots or create a custom real-time snapshot. For less critical data,
you do not need to create frequent snapshots or retain backup copies.
enables you to control the costs of using backup. For each VM in your storage
cluster, you can schedule hourly, daily, or weekly snapshots. The maximum
frequency for any specific VM is once per hour. Hourly setting is in 15 minute
snapshots are taken each day, given the following settings.
Each day these
snapshots are taken.
- VM 1 hourly
snapshots to run at hour:15 minutes, between 10 PM and 1 AM.
- VM 2 hourly
snapshots to run at hour:30 minutes, between 8 PM and 12 AM.
- VM 3 and 4
hourly snapshots to run at hour:45, between 6 AM and 8 AM.
- VM 5 daily
snapshot to run at 6:00 AM
- 6:00 AM — VM 5
- 6:45 AM — VM
3, VM 4
- 7:45 AM — VM
3, VM 4
- 8:30 PM — VM2
- 9:30 PM — VM2
- 10:15 PM — VM1
- 10:30 PM — VM2
- 11:15 PM — VM1
- 11:30 PM — VM2
- 12:15 AM — VM1
Notice that the last
snapshot is before the ending hour:00.
To schedule a
snapshot every hour over 24 hours, set the start time, then set the end time
one hour before. For example, hour:15, start 4 PM, end 3 PM. This takes a
snapshot at 4:14 PM, 5:15 PM, ... 12:15 AM, 1:15 AM ... 2:15 PM, 3:15 PM. Then
restarts the 24 hour cycle. Note: The maximum number of snapshots per VM is 32.
So, you could only take an hourly snapshot up to 32 hours.
snapshot displays the set time for the snapshot based on the current time zone
setting for the storage controller VM. So, if a snapshot was set at 7 pm PST
and the storage controller VM time zone is changed to EST. The next time you
open the scheduler window, it automatically updates to 10 pm EST.
