Hacking Backup clean nand again?

[griffiet]

Hi all -

Questions about best practice - using Atmosphere for CFW and have setup emuNAND for CFW and have a clean sysNAND at 8.1. I have two clean backups, one at 6 something and another at 8.0.

I don't care about fuses so have normally updated sysNAND in OFW.

The question is - I have two clean backups in case of problems, but wondering if I should take a clean NAND backup after every OFW update. So would make one at the current 8.1, update to latest OFW and make another at 9.1 etc. Worth it? Or am I wasting a bunch of time and worry? I feel like I could always boot from Hekate, restore one of my older backups, boot from Hekate to OFW and update online. Or is updating the same console to a given firmware twice asking for a ban?

Thanks!

Only NAND backup made prior to going online is considered clean, anything made after running CFW is tainted.

Have never been online in emuNAND/CFW, kept in Airplane mode and no Wifi info entered. Have been online with sysNAND. Are you saying sysNAND is tainted by having run emuNAND CFW with no network connection and no longer worth backing up? Just restore to my stock pre-any-CFW install?

Thank for the help - just want to be certain I'm doing the best to preserve my system.
