@jeelet I yet to write a document for backup and restore
We can backup the storage database in two formats. 1. JSON, 2. YAML
NOTE: Metric database(influx db) backup not covered by MyController v2, you have to do it manually

steps to run backup

1. Setup add a backup handler

• Operatons >> Handlers click on Add
• Enter the details as follows
• 

2. Run manual Backup

• Add backup locations in Settings >> Backup and Restore >> Backup Locations
• 
• Click on Settings >> Backup and Restore >> Backup
• 
• Click on refresh button in Settings >> Backup and Restore
• 

3. Setup automatic backup

• Add a schedule to run a backup in Operations >> Schedules
• 
• handler parameter backup_yaml as follows
• 
• automatic backup scheduled for every 6 hours once

Please let me know if the steps are not clear.

(it's easy once you understand it)

two questions about backup

1 : the cycles of backup program overwrites the old backups ? or it is incremented ?

2 : for the restoration, example.
---- installs new-----
- a new blank installation of myC

• copy and create the directory /opt/backups/ with the backup in it, then launch : Settings-->Backup Restore

@JeeLet said in Backup Config:

1 : the cycles of backup program overwrites the old backups ? or it is incremented ?

Each backup is a full snapshot of MC. Each is written individually. You can choose how many backups you want to keep to save disk space. In the example above it is 8 backups shown in the "Retention count" option.

So if you backup daily you will always have the last 8 days snapshots available. If you backup hourly you will have the last 8 hours available.

Hope that is clear for you!

2 : for the restoration, example.
---- installs new-----
- a new blank installation of myC

• copy and create the directory /opt/backups/ with the backup in it, then launch : Settings-->Backup Restore

This restores the entire MC snapshot with all the settings and data preserved.

@JeeLet , what @skywatch is explained exactly.
In addition to that,

• MC v2 never take backup of your metrics database, here it is influxdb
• Retention count - controls only that particular backup schedule, example: if you run a backup manually, it will not be included in the count and it never deleted. also it will not count backup from another schedule. in MC v2 it is possible to schedule multiple backups. I have like weekly and hourly.

thank you for this clear explanation guys

. the backup of infuxdb

the one recopy with the tree command

@odroidc2:/var/lib$ tree influxdb

├── influxd.pid

└── wal [error opening dir]

@odroidc2:/var/lib/influxdb/data$ sudo tree mycontroller

and thus to save
