As an FYI there will be reboot of the server at around 01:00 tomorrow morning to finalise the backup installation.
I'm probably also going to schedule a full-metal restore backup for sometime the following night and while there will be some impact, I can't be sure just how much it will slow down the server. I'm going to exclude the database directory from both and retain the current 04:00 separate backup for them in order to minimise the impact. Cheers Russ

The reboot was fine.
I'm going to kick off the initial backup shortly as it might take a while to run. I'm expecting that there will be an impact on sever performance during the backup but it's very much a case of 'suck it and see' as there isn't really any way of knowing in advance. If it sucks up too much of the server resources, I'll stop the task. Cheers Russ

Pleased to say it had no service impact and the full ~200 Gb back-up took about 56 minutes.
It did increase utilisation of both CPU and RAM but not to levels that were of any concern. The new schedule for daily backups will be: 03:00 Database backup (~5-6 minutes) and it does severely impact service because the tables are locked while it is being done to stop changes being made. 03:15 Database backup is moved to a location where the backup will find it. No impact. 03:20 Database backup is compressed. No impact. 04:00 Server backup is performed of changed files only. Expected to take only a few minutes and have no service impact. Regards Russ
