Snapshots

A snapshot is a restorable point-in-time picture of a VM or Private Cloud storage. Snapshots can be used to revert either individual virtual machines, or an entire Private Cloud instance back to the snapshotted state. Snapshots can be run either as part of a schedule or on-demand. Snapshots are particularly useful in the event of a misconfigured environment, as restoring from a cloud snapshot can revert the entire environment to its previous state. There are two types of snapshots:
  • Cloud Snapshot
* A snapshot of an entire Private Cloud instance.
  • VM Snapshot
* A snapshot of an individual Virtual Machine.

​
Snapshot Profiles

Snapshots are created by using snapshot profiles. Once a snapshot profile is set up, it can be set to automatically snapshot machines on a regular basis according to stored schedules. The retention period, frequency, and machines snapshotted are all configurable. A snapshot profile can be assigned to an entire Private Cloud, an individual VM, or a NAS volume. Private Cloud includes multiple default snapshot profiles that can be used out of the box or modified as needed. Users can also create new snapshot profiles from scratch. Default Snapshot Profiles Default profiles are readily available and can be modified if needed. The following are default snapshot profiles:
  • SOX**(Sarbanes-Oxley)**
* Yearly snapshots retained for 7 years

* Monthly snapshots retained for 1 year

* Weekly snapshots retained for 31 days

* Daily snapshots retained for 7 days
  • HIPAA (Health Insurance Portability & Accountability Act)
* Yearly snapshots retained indefinitely (no expiration)

* Monthly snapshots retained for 1 year

* Weekly snapshots retained for 31 days

* Daily snapshots retained for 7 days
  • NAS****Volume Syncs
* Daily (at 6pm) snapshots retained for 3 days
  • *Cloud Snapshots (Suggested default profile for entire-system snapshots)
* Hourly for 3 hours

* Daily (at midnight) snapshots retained for 3 days

* Daily (at noon) snapshots retained for 1 day
Any of the default profiles can be modified to meet individual needs or requirements.

Using a Default Snapshot Profile

  1. Click System.

  1. ClickSnapshot Profiles and a list of default snapshot profiles appears.

  1. In this example, we’ll show the SOX profile, which was created for compliance focused orgs, but MacStadium recommends Cloud Snapshots for normal use cases.

  1. Double-click SOX row, and the SOX****Snapshot Profile opens.
Screenshot 2024-11-13 at 2.29.23 PM.png The default SOX snapshot profile has 4 periods:
  • A snapshot is taken Daily. It is retained for 7 Days.
  • A snapshot is taken Weekly. It is retained for 4 Weeks.
  • A snapshot is taken Monthly. It is retained for 1 year.
  • A snapshot is taken Yearly. It is retained for 7 years.
NOTE : There is a + Add Period , which can be used to add more snapshots. For example, a user might want an hourly snapshot or a 6-hour snapshot. The retention time can also be set.
  1. In this example, click the + Add Period to modify the existing default snapshot profile. The Snapshot Profile Period screen opens.
Screenshot 2024-11-13 at 3.02.28 PM.png In this example, an hourly snapshot profile is created and the retention period is 3 days. This means every hour a snapshot is taken, and then it is kept for 3 days, causing 72 snapshots to be stored.
  1. Click Submit to create the new snapshot profile.
Screenshot 2024-11-13 at 3.23.41 PM.png This snapshot profile now has the following snapshots:
  • Hourly
  • Daily
  • Weekly
  • Monthly
  • Yearly
Depending on individual needs and circumstances, this snapshot might be capturing too much or too little data. But it is important to remember that snapshots can be modified as needed, and starting with a default snapshot profile might be helpful. For new users who do not have any snapshot profiles assigned, MacStadium recommends enabling the default Cloud Snapshots profile for Cloud snapshots. This profile stores 3 days of snapshots at varying frequencies, enabling recovery to a recent state in the event of a misconfiguration.

​
Cloud Snapshots

The Cloud Snapshot profile determines the schedule used for creating snapshots of the entire system. MaStadium recommends setting a Cloud Snapshot profile to for most Private Cloud instances. Scheduled Cloud Snapshots are disabled by default. To enable cloud snapshots, a profile must be selected by navigating to System → Cloud Snapshots , and select the snapshot profile to use. If a Cloud Level Snapshot is configured, individual VM snapshots may not needed. Cloud Snapshots include every VM and volume in a Private Cloud instance, and are taken in addition to VM snapshots.

​
Enabling Cloud Snapshots

  1. From the main dashboard, click System on the left menu.

Manually Creating a Cloud Snapshot

  1. From the main dashboard, click System from the left menu.
  2. Select Cloud Snapshots.
  3. Select New from the left menu.

  4. The Cloud Snapshot screen opens
  • Enter a Name (required) for the snapshot.
  • Enter a Description (optional).
  • In the Expires field, Select/Enter a date and time for expiration.
In the Expiration Type field, Never Expire can be selected, however, this can cause the snapshot to consume substantial amounts of storage. It is not recommended to use the Never Expire option unless absolutely necessary. Screenshot 2024-11-15 at 11.49.11 AM.png
  1. The Private checkbox is selected by default. This option pertains to multitenancy, and can be ignored in the majority of cases.
  2. Click Submit.
