Let’s say I want to backup 100GB of data using restic and i run the backup command daily for 7 days, over the 7 days 1 GB of data is changed. At the end of this, how big would the repo be?
Hey and hello!
The size of the repository after the initial backup and the subsequent backups depends entirely on how well the data deduplicates. If you have a lot of similar text files, they will deduplicate highly compared to a lot of different binary data. It’s really impossible to say without knowing more.
I suggest you try it. You can rest assured that it will not take more than 101 GB (besides a little bit of space for the actual files keeping track och snapshots, indexes, packs, etc), that’s for sure
It will most likely take notably less than 101 GB, as presumably some of your data will deduplicate fine.
