12. Managing Application Snapshots¶
Application Snapshots
An application snapshot is a reference marker for an application at a particular point in time. It contains a copy of the application’s data plus the application’s current state. Snapshots provide a safeguard against application data corruption. For example, if key application data is accidentally deleted, a snapshot can be used to revert (roll back) the app to a point in time before the deletion occurred.
Taking snapshots of storage volumes has existed for decades in the industry. However, when an application is distributed and/or uses multiple storage volumes across one or more pods, orchestrating storage-only snapshots across all of them is tedious, error-prone and inconsistent. Storage-only snapshots are also unaware of the application configuration and its topology, which makes cloning, backing up or restoring cumbersome and prone to misconfiguration.
Robin allows creating application-consistent snapshots of an entire application, which capture:
The entire application topology and its configuration (i.e., specs of Pod, Service, StatefulSet, Secrets, ConfigMaps, etc)
Snapshots of all data volumes (PersistentVolumeClaims)
Robin snapshots at the storage layer use redirect-on-write, which means that snapshots can be taken in less than a second even for terabyte sized data volumes. Because only the changed blocks are tracked between snapshots, Robin snapshots are very space efficient.
Topics covered in this chapter:
|
Snapshot an entire application (data and metadata) |
|
Delete the snapshot of an application |
|
Restore a snapshot from a backup copy stored on an external storage repository |
|
List snapshots for one or more applications |
|
Show detailed information about a specific snapshot |
12.1. Create an Application Snapshot¶
An application snapshot is created using this command:
# robin snapshot create <snapname> <app_name>
|
A name that would be assigned to the snapshot being taken |
|
Name of the application being snapshotted |
Example:
# robin snapshot create mysql3 --wait
Job: 331 Name: ApplicationSnapshot State: VALIDATED Error: 0
Job: 331 Name: ApplicationSnapshot State: WAITING Error: 0
Job: 331 Name: ApplicationSnapshot State: COMPLETED Error: 0
# robin snapshot list --app mysql3
+----------------------------------+--------+----------+----------+----------------------------+
| Snapshot ID | State | App Name | App Kind | Snapshot name |
+----------------------------------+--------+----------+----------+----------------------------+
| b6033a5a4d6a11eab805255c7aa2236e | ONLINE | mysql3 | ROBIN | mysql3_snapshot-1581493122 |

Creates an application snapshot.
End Point: /api/v3/robin_server/apps/<app_name>
Method: PUT
URL Parameters: None
Data Parameters:
action: snapshot- This mandatory field within the payload specifies the snapshot operation is to be performed.snapname: <snap_name>- This mandatory field within the payload specifies the name of the snapshot.quiesce: <list_of_quiesce_options>- Utilizing this parameter by specifiying a comma seperated list of quiesce options results in them being exercised in order to acheive a consistent application state. Valid values include: ‘fs’, ‘container’ and ‘all’. Note this option is only valid for ROBIN applications.

12.2. Configuring snapshot schedules and retention policies¶
This is covered under the Manage Application Snapshot Schedules section of
Applications chapter. See details of the command robin app snapshot-schedule.
12.3. Delete an Application Snapshot¶
In order to delete an application snapshot, issue the following command:
# robin snapshot delete <snapshotid>
|
Unique ID of the snapshot (obtained from the output of |

# robin snapshot list --app mysql3
+----------------------------------+--------+----------+----------+----------------------------+

12.5. List Application Snapshots¶
Issue the following command to list application snapshots the current user is entitled to view:
# robin snapshot list --app <app_name>
--app-kind <app_kind>
--app-namespace <app_ns>
--level <level>
--verbose
|
Only include snapshots for the specified applicaiton instance |
|
Filter by application kind (valid choices are ‘robin’, ‘helm’, and ‘flexapp’) |
|
If there are multiple applications of the same name but in different namespaces this option can be used to distinguish them. Note this option is only valid when |
