is Rsync not the same as Raid 1? Raid 1 is more up to date with backup (instance) and Rsync more like a day, depends on the settings. Also i have seen some other type of backup methode, like ZFS and BTRFS and an application called time shift (something like making an snap shot) i dont f this is available for the raspberry
Could that be more alternative solution? i am kinda noob in backing things up
To make an all in one server i will take the nightmare in consideration, i think that is not really a big problem, as long the data is secure on the HDD. Its more likely that the SD card is gonna fail. So the OS and the settings, ill back this up in one image and if it fail ill restore on the new SD card.
to be honest its more like an hobby to store my personal data,
by the way i got the enclosure raid HDD from the brand Orico, the transparent version dual bay , i didnt tried it yet, but soon. The first thing i see, there is no fan the cool the hdd
i dont know if this is good for the HDD.
2 server is kinda overkill i think, for my situation
thanks for your suggestion. I`ve look into that and i can see that is very lightweight os, maybe ill should use that instead of raspbian, i am even more confuse, like more doubt which one to use
Further more i want to add more services ! haha
all in one printer and scanner (pixma mp 270) server and samba. Not ideal to add more service.
Also should i put OS on the SD card or on the USB boot (hdd or SSD) for longevity? I saw that the most SD card died after one year using as server.
Thank you all for the ideas and input, if you have more suggestion please keep posting
So for now
SDcard or USB boot (HDD of SSD) not sure yet
OS = still got doubts Raspian or diet pi
Backing up = Rsync
