Hyper backup , compression or not ? 1 hdd daily backup , 1 hdd backup one time or monthly

[PSP.]

Hello ,
I can't decide , I have 2 of 2tb external hdd's , not sure what compression doing
1 daily backup ,
1 monthly or any new update just spare ,
but compression option will reduce quality of image and videos ?

I would assume backup compression is lossless. What software in particular are you talking about, does it have any specific options for images and video?

 

Ah, missed that you're talking about Hyper Backup. It is using lossless compression, it won't re-encode your images and videos. Whether compression is worth it depends on how compressible that data you're backing up is. If it is mostly images and videos (which are already compressed formats), it won't provide much or any additional compression.

basically what compression meaans tho, if the company goes out of business it could render your backups useless. 

 

that's why i always clone, you could at least always read your files.

If you backup to the cloud and the company goes out of business, your backup is gone, regardless of compression or not. If you backup to your own hardware and the software you use still works, you don't have to care whether the manufacturer/developer is still around.

As I said, it really depends on what you're backing up. If it is mostly text files you can save a ton of space. If it is mostly images and video, compression isn't going to do much, since the files are already compressed.

 

No compression is going to be faster, and easier to access without requiring specific software. So in that sense I agree with @Mark Kaine, it's usually the more sensible option. Compression primarily makes sense if you have a ton of (highly compressible) data and can't afford disks that are big enough.

backing up non compression first drive videos for plex Anime and movies  + Synology photo all with videos  + Synology drive .rar files + app's checked everything , second drive will test compression 

was worried  to lose videos quality I did many things , 
so compression or not fine then
