you may be prompted for username/password if the SSH pub key hasn’t been added to the SFTP server, this is OK for the initial setup, however scheduled/automated backups will fail

If you are restoring a node in a multi node deployment you will see an additional message of

Checking number of admin nodes
number of admin nodes :x
Yarnman is in distributed mode
Check couchdb replication on other nodes is healthy and after 5 minutes reboot yarnman or run systemctl stop yarnman.service and systemctl start yarnman.service

This is to allow replication to all nodes, to prevent any schedule jobs/ reports from rerunning from the last backup

Rebuild Disaster recovery

Pre-Req

  • Deploy new OVA with same version as the backup

  • Setup as a new install (eg Configure with ip, user/pass, generate certificates if prompted)

  • install yarnman

  • confirm can reach appadmin webpage, Do not Login or Accept the EULA as we will restore over this.

  • Setup backup to same repo for the node to be restored, Do Not initiate the repo or preform a backup

A new SFTP/SSH key will be created, this will need to be added to the backups server for future automated backups to function again. interactive (user/pass) can be used for a restore , if the new ssh key can’t be added to the backup server at time of restore.

the Hostname doesn’t need to be the same as the restore backup, however any new backups will backup with the new hostname.

If building with a different IP address, Replication will need to be adjusted to the new IP address as well as Clevin/Tang if setup.

Run the following, Refer to previous detailed command instructions if required 

sudo ym-backup-setup.sh 
sudo ym-backup-actions.sh -p sftp -a sftp-user-setup
as root user ;  sudo -u ym-backup-user ssh-copy-id -i /home/ym-backup-user/.ssh/id_rsa.pub sftpbackup@10.101.10.86
sudo ym-backup-actions.sh -p sftp -a sftp-setup-connection
sudo ym-backup-actions.sh -p sftp -a snapshots
sudo ym-backup-actions.sh -p sftp -a restore -r xxxxx

The restore script will warn we are restoring to a different node, Continue.

Alternate Manual Method (not recommended)

*** snapshot command doesnt work in manual mode yet, also requires sudo ym-backup-setup.sh to be run ?
