Type |
Type of backup job to create: Run now or
Scheduled. |
Schedule |
Schedule backup settings by date and time. Only appears when
Schedule is selected as the Type. Available settings:
- Date: Day, Month, and Year.
- Time and Timezone: GMT is the default timezone. To change the timezone, click
GMT, select the country and timezone, and click
Save.
- Repeat or Don't Repeat settings: Use to schedule a backup job on a regular
periodic basis, or run a scheduled backup during off hours.
|
Keyspaces |
Required. Allows selecting one or more or all keyspaces for a backup. When
backing up a DSE Graph database, select your graph keyspace. When a keyspace is
created in DSE Graph, it is actually comprised of three keyspaces that OpsCenter
bundles together because all three keyspaces are required for a DSE Graph
backup. Tip: Click the plus (+) icon to
select one or more options. To keep the list open when making multiple selections,
press and hold the Cmd key (Mac) or Ctrl key (Windows/Linux). |
Datacenters |
Required. The Datacenters field only appears if there are multiple datacenters
configured for a cluster. Allows selecting one or more or all datacenters for a
backup. Running a backup by a specific datacenter improves backup performance under
most circumstances, because the process eliminates backing up data redundantly since
the data is replicated to other datacenters anyway. Warning: When limiting a backup by datacenter, if the SimpleStrategy
replication strategy is used, or the NetworkTopologyStrategy is used with a
replication factor of 0 for a datacenter, the snapshot might not contain all the
data for the cluster. Tip: Click the plus (+) icon to
select one or more options. To keep the list open when making multiple selections,
press and hold the Cmd key (Mac) or Ctrl key (Windows/Linux). |
Alert on Failure |
Activates an alert upon backup failure that sends an alert to the event log.
Default: False. Tip: Enabling Alert on Failure
is particularly useful for monitoring scheduled overnight backups. Configure alerts for events and
route the alerts through email, or post
URLs to a chat room such as HipChat or Slack. |
Current Data
Size |
Current data size is a best estimate of how large the snapshot will be based on
the currently selected keyspace or keyspaces. The information is based on table
metrics collected by OpsCenter. Current Data Size is a dynamic read-only field that
displays Unknown when size information is not available for
the selected keyspaces. An Unknown Data Size typically displays when either a system
keyspace is selected or keyspace size information has not been collected
yet. |
Location |
Snapshots are saved to the node's snapshot directory for the table being saved.
For example,
/var/lib/cassandra/data/OpsCenter/settings/snapshots. Add
more locations to back up to and restore from, including Local file system and
Amazon S3 locations, by clicking Add Location. Set a
retention policy for the backup data in each location of a backup job. See Adding a backup location. |
Staging Directory |
The location of the Backup Service staging directory for backups. The default
location is /var/lib/datastax-agent/tmp. To change the default
location of the directory, indicate the path using the tmp_dir configuration option in
address.yaml. |
Advanced Options |
Expands the Pre-Backup Script and Post-Backup
Script fields for running scripts before or after (or both) snapshots
are taken. The script must be located in the appropriate install directory on each
node.Custom backup scripts must be located in:
- Package installs:
/usr/share/datastax-agent/bin/backup-scripts
- Tarball installs: install
location/agent/bin/backup-scripts
For
details, see Configuring custom scripts to run before and after backups. |
Create Backup |
Creates a scheduled or runs an ad hoc backup job immediately depending on the
selected backup Type (Scheduled or Run Now). |
