Backup

To backup, you must run all commands on the primary and minion systems unless otherwise noted. Perform all steps on all standalone servers.

To backup the Carbon Black EDR server:

Stop Carbon Black EDR services.
1. Copy and save all entries in the Carbon Black server section from /etc/hosts that are marked by {{BEGIN - CB Server}} and {{END - CB Server}} comments to a remote location. There might not be a Carbon Black server section, or the section might be empty.
2. Issue the following commands to back up files. (Not all files exist on some systems or installations.)
```
tar -P --selinux -cvf cbssh.tar /etc/ssh/
tar -P --selinux -cvf cbconfig.tar /etc/cb/
tar -P --selinux -cvf cbrootauthkeys.tar /root/.ssh/authorized_keys
tar -P --selinux -cvf cbinstallers.tar /usr/share/cb/coreservices/installers/
tar -P --selinux -cvf cbcrons.tar /etc/cron.d/cb
```
3. You can perform a full backup, or you can skip event core backups if migration space is limited. Issue one of the following commands.
  
  Full backup:
```
tar -P --selinux -cvf cbdata.tar /var/cb/
```
  Backup without event core:
```
tar --exclude=/var/cb/data/solr?/cbevents/* -P --selinux -cvf cbdata.tar /var/cb
```
4. Back up custom changes from the following locations:
```
/etc/rsyslog.conf
/etc/rsyslog.d/
/usr/share/cb/syslog_templates (on primary machine only)
```
5. Custom syslog changes might be specified in the /etc/cb/cb.conf file. Search the file for any SyslogTemplate= entries. For example:
```
WatchlistSyslogTemplateBinary=/var/custom/syslog/ watchlist_binary_custom.template
```
Save tar data to a remote location.
