You have seen this a million times, but i have a question no one seems to quite answer
- running OMV 4.1, G2020 core-duo @2.9GHz, 8 GB ram
- ALL IMPORTANT DATA IS BEING SYNCED TO AN EXTERNAL DRIVE. every thing else is expendable.
- HDD layout (all drives WD RED and NTFS: why? previously in windows rig):
|--- 1x 2TB (hardware failure): it wants to change careers and become an angle grinder
|--- 2x 3TB (working normally - 2-3 years old - probably same batch)
|--- 2x 4TB (newly bought - probably same batch)
|--- 1x 4TB 2-3 years old and had MFT corrupted. Restored to external and newly wiped
I will be moving everything to ext4 after i deal with the below question
When i lost my 2TB drive i didn't care much for the data (anime + movies), but it is irritating to just lose data from hardware failure.
I found out how raid 5 works and i though it is a good idea (i have 3x4TB drives ready)
after reading the forums, i realized that raid is problematic and a pain to deal with
QUESTION 1: i am willing to buy 1 extra drive for every 2 storage HDDs i have, but is RAID 5 a solution to my situation? I just want to have a REASONABLE protection from hardware failure, nut a full backup. I also don't care about uptime, i just want to be able to get my date back if possible.
QUESTION 2: is there a better way (snapshot backup, non-raid striping, whatever.......) to keep redundancy other then full blown 1-to-1 backup? I want to be efficient with storage capacity, 1.5-to-1 ratio is acceptable
QUESTION 3: memory is limited to 12 GB ram max (mix and match). Which File system is recommended to move forward to. ext4? BTRFS? ZFS?
QUESTION 4: since i am going to be removing most references to shared folders and the such, is there any reason to upgrade to OMV 5 while I'm at it?
|--- I am a programmer, and i am trying to move to linux as my daily OS (manjaro KDE Plasma), but i am an UTTER NOOB at it, so i don't know which tools to use in linux.
|--- all non-backuped data on the server are large video files and games files (bit degradation is not a big problem.... not much)
|--- 4mbps internet => off-site backup is not an option
