Backup HBase tables
Follow these steps to back up atlas_janus table.
- Go to HBase Shell.
- Disable atlas_janus and ATLAS_ENTITY_AUDIT_EVENTS tables.
- Create a snapshot of the atlas_janus and ATLAS_ENTITY_AUDIT_EVENTS HBase tables.
-
(Optional step) If the backup needs to be preserved on the local file system,
then use the additional command to copy it locally.
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot 'atlas-janus-backup' -copy-to /path/to/backup/location
The above steps can be performed using the following commands from HBase shell.> disable 'atlas_janus' > snapshot 'atlas_janus', 'atlas-janus-backup' > enable 'atlas_janus' > exit
> disable 'ATLAS_ENTITY_AUDIT_EVENTS' > snapshot 'ATLAS_ENTITY_AUDIT_EVENTS','ATLAS_ENTITY_AUDIT_EVENTS-backup' > enable 'ATLAS_ENTITY_AUDIT_EVENTS' > exit
