First of all, thanks for building restic.
Exponential Increase in Backup Storage
We are using restic with backend AWS S3. I notice that every time backup runs, the storage space increases by current server space, though it is incremental backup.
The first backup stored 30GB. The second the time the command was run, the storage space used is 60GB, even though very few files were added, less then few KBs.
The command I use to schedule backups:-
/usr/bin/ionice -c2 -n0 restic --quiet --host servername backup / --exclude=*.log
I was expecting only increment data to add up to the storage. Am I doing something wrong?
We are currently using restic_0.9.4_linux_amd64 binary.
Also the backup takes a lot of time. In another case, I saw first backup of 17GB on VPS take 32 hrs.
The storage and server should be like 50-70ms apart. I was running with nice -n19.
I am currently testing without “nice”.
Next, I may try with other options of ionice. Anyone tested with ionice can make any recommendations?
