I – In Which Case Should We Use This Process?
With Qnap 4.1 Firmware, I realize that Qnap backup configration files (not data) once in every week, and good part is you can restore any configration, or complete configration easly with a few steps!
.
When should we use this?
We easly fix 2 cases by this way;
Case 1: We have iscsi image files, but iscsi_trgt.conf was currupted -> We restore with only copying iscsi_trgt.conf
Case 2: RAID 6 & users rights on Qnap was corrupted -> We restore with complete configration restoring
Must warn that this process will not recover accidently deleted files, but can fix RAID problems or accidently lost folder permissions configration easly.
MY ADVİCE İS DONT DO THİS ALONE IF YOUR NOT SURE WHAT YOUR DOİNG. THİS MAY CAUSE QNAP UNEXPECTED CORRUPTİON, AND PLEASE CONTACT WİTH OFFİCAL QNAP SUPPORT TEAM IF YOU GET THİS KİND OF PROBLEMS!
