Have moved from another backup solution to urbackup and must say first impressions are excellent indeed.
Looking for some advice. I have 11Tb of backup space in my /urbackup_data directory.
I have a fileserver that I backup amongst other clients, but this file server has around 7Tb of file that don’t change often, incremental additions only. So, a “full file backup” is 7Tb.
I have set up as below;
Interval for incremental file backups = 24 hours
Interval for full file backups = 30 days
Maximum number of incremental file backups = 20
Minimum number of incremental file backups = 10
Maximum number of full file backups = 1
Minimal number of full file backups = 1
The bhaviour I want to to create a baseline ( full backup ), then have incremental backups follow the rolling window as above.
30 days later I want the “full file backup” data to be updated so it’s effectively a new baseline. My fear is that in 30 days the server wil try and write another 7Tb of data.
This duplication of the 7Tb obviously I don’t have the space for. When I manually run a second “full file backup” it seems to be backing all the files up again…
Is the behaviour in my confiuguration above that the second “full file backup” ( if I had the space… ) would be written, then during the cleanup process the incrementals removed and the first “full file backup” removed also?
What would be the best confuration for what I need?
