In case of any errors during backup,
debops.rsnapshot role collects output
of all scripts and sends it if anything shows up to
account. With default debops.postfix configuration, this account is aliased
root account, so all e-mails should be forwarded to the system
Logs for each server configuration are stored in
directory, and are automatically rotated.
Fixing issues with SSH host fingerprints¶
When hosts are reinstalled, SSH host fingerprints might be changed in which case :program:`rsnapshot will send e-mails to system administrator. To fix these errors, you can use a special set of a variable and tag:
debops --tags role::rsnapshot:sshkeys --extra-vars='rsnapshot_reset_sshkeys=True'
This command will remove all known SSH host fingerprints from
/root/.ssh/known_hosts on the backup clients and rescan the hosts, as well
as reinstall the :program:`rsnapshot SSH keys on backup servers if necessary.
rsnapshot_reset_sshkeys variable, if
True, will always remove SSH host
fingerprints, therefore it shouldn’t be used in the Ansible inventory to avoid
