That looks pretty conclusive to me. What needs to be clarified. [4,0,12,0,0,0,10] 4 backups at 1 week 0 backups at 2 weeks 12 backups at 4 weeks 0 backups at 8 weeks 0 backups at 16 weeks 0 backups at 32 weeks 10 backups at 64 weeks The monthly backups are actually slightly less than a month. If you want a full year, you should do 13 of them. The yearly backups at 64 weeks are actually about 14.7 months apart, so they're not quite yearly. You could increase the number of monthly backups if you want full coverage or switch to 32-week backups instead. Keep in mind that due to pooling, backups do not take up nearly as much space as you expect (only enough to account for the changed files), so you will be able to keep many more backups than you think you can. -- Bowie ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
