Backup errors have been found to be caused by multiple issues including
Insufficient disk space
If there is insufficient disk space in the destination, the following error is shown:
backup strategy "": 1 error occurred: * send snapshot volume "repld999ede1_oracle-backup" request to uu3zsh2qs3ajkk6oxasfoa0rx: snapshot volume: snapshot failed with exit code 255
To resolve this, increase the disk space available on the target backup server or reduce the number of snapshots being maintained in the dashboard.
Backup service not running
If the backup service has failed, then the following error is shown:
backup strategy "": get server init: wait for server: make https request: Get https://replicated_replicated:9878/v1/ping: dial tcp 10.0.0.3:9878: connect: connection refused
To resolve this, restart the server.
The snapshot service requires a valid key pair in order to authenticate to the SFTP server. The keys must be generated on the Rally services VM, uploaded to the SFTP server and the correct PEM file must be copied into the dashboard of the services VM.
