Backups in CycleCloud
By default, CycleCloud will take point-in-time snapshots of the underlying application datastore as recovery points. These are stored in /opt/cycle_server/data/backups/. The backups directory does not have stringent read-write IO or latency requirements, so it is often mounted to an NFS share or blob fuse for additional durability.
Important
Within this directory is also a sub-directory named shared/, which holds data common to all backups and must be preserved to enable restoration.
Backup Schedule
By default CycleCloud will preserve snapshots for:
- 5 min
- 15 min
- 1 hour
- 4 hours
- 8 hours
- 1 day
- and 7 days
The backup schedule is stored as a datastore record of type Application.BackupPlan. To access this record, go to the Settings page and select the Records tab. Make sure All record types are selected in the drop down. Near the very bottom of the list is a category labelled Backup Plan. Using the edit option, the schedule list can be changed and saved.
Restore from Backup
The backups are stored with the restore time encoded in the directory name: /opt/cycle_server/data/backups/backup-2018-08-30_15-05-05+0000. This directory is a restore point. To revert CycleCloud back to this point in time, run the restore utility with this restore point as the argument. If no restore point is specified, then the latest restore point is used.
cd /opt/cycle_server/
./util/restore.sh ./data/backups/backup-2019-08-30_15-05-05
