Is there any way to consolidate backup-data from incremental Rnsapshot backups?
My problem: Disksize on backup-drive is getting low, since i had and still will have some bigger data moves inside my datastrukture. (ex. import of photos of a year, correction of a typo in a parent-folder). All of these causes a copy instead of a hardlink, even though there's actually no change of the data itself.
Is there a possibility to deduplicate the data? I'm shure, that there will be a quite big potential to save data size.
google got me to a program called "hardlink" ( https://manpages.debian.org/st…rdlink/hardlink.1.en.html or https://www.dinotools.de/2013/…atz-sparen-mit-hardlinks/ )
Has anyone experience with this?
I'm Linux-beginner, everytime again, when I've to maintain my NAS. Therefore I was not able to test it myself (probably caused by to old OMV 2.2-Version... not shure about that)
every advice highly welcome!
