Differential backup file naming
Below are file names for my backups sorted in date order. I have the operation scheduled upon system shutdown, once a day only. Backup method differential/ create a full version every 6 differential versions/ store no more than 3 version chains. I am struggling to understand how this is working. In particular, why b1_s1_v1 through to b1_s7-v1 when specify to create a full version every 6 diffs. And why, having created a fullbak b2_s1_v1 and diff_b2_s2_v1, does it revert to b1 for b1_s8_v1 and on?

Thanks Pat L - I don't think I edited my settings but if that can cause this then I must suppose I did.
