WinPE and duplicati as Disaster recovery solution is trying to take WinPE plus Duplicati and turn it into a BMR solution which previously used BURP which is also file-level. Windows disaster recovery with WinPE and burp. Initially I was skeptical that Duplicati could create all the odd files, but apparently it does. Not sure about Linux.
Personally I take a Macrium Reflect image on a portable drive (especially before a Windows version upgrade), however my only remote backup is file-level of my data only, the theory being that the rest is easier to replace.
Boot into Duplicati via CD or disc on key? is a current discussion from someone wanting something near BMR, however there’s also a discussion of how to get Duplicati to do fast file-level restore without big database wait. Please feel free to toss on any ideas I missed. To me, this is an impediment to those who want fast recoveries.
