Hi I have a decent volume of media files and also a decent volume of files and other data. I do "software raid"/sync across a pair of 24 TB Hdds and a pair of 14 TB Hdds on my main desktop which also acts as my Plex server for the time being.
Backup wise, I am limited in means so I have 1 external 18TB Hdd which i want to act as the offline backup for the 24TB pair for the time being since I'm not close to 18TB data on the 24TB yet. And I do have a 14TB external drive to act as offline backup for the 14TB mirror.
QUESTION:
For this offline data, is it better to just use macrium to image the drives/folders and this way allows me to have multiple images of the same drive/folder as a sort of time machine, storing different instances of thse drives (I assume this is possible because macrium compresses) image files? If not is there an app that creates compressed backups of folder/drive images?
OR is it better to just have these offline drives be an exact mirror of the drives inside my desktop?
