I am running linux (Kubuntu 19.10)
I just started using restic as a better backup solution than what I have mostly done (by copying entire home directory manually to external hdd.)
Using restic will ensure that all data, at all times is backed up. I have about 180,000 files (707GB) of data in my home directory which when backed up with restic is 137,000 files (684GB).
I have never backed up that many fails at one copy operating before, i’ve only done it over a course of a week or so by manually copying certain folders under my home directory until i got everything over.
Now I always try to make backups of backups at certain times to ensure if one backup drive malfunctions, I got another. This seems based on its copy speed like it would be copying much slower than when restic originally performed backup.
When I did a backup with restic command was: ./restic -r path/to/repo --verbose 2 backup ~/
After backup was done (and ran restic check), i plugged in another external hdd to perform the copy of this newly made repo to it. I did that with rsync using command: rsync --delete --delete-after -a --info=progress2 path/to/source path/to/destination (I know the --delete flags wont matter during it’s first copy, but will be used for future operations).
The speeds are anywhere from 25-40mb/s when it first started. After about 20 minutes or so, it went down to average of 15mb/s and hardly goes up to 16mb/s so it stays around this average speed unless restarted. Now I understand that copy 100,000 files of smaller sizes can tend to take longer than a few big sized files but I dont understand how this rsync operating will take longer than the original backup when the original backup performs more operatings all together such as encryption & compression.
In case it matters, all my external hard drives are fully encrypted with veracrypt. My internal disk encrypted with luks.
It doesn’t seem like backup a restic repo of 137,000 files should take longer than backing up 180,000 files not part of restic repo.
I did boot into a live linux disc and tried the copy using rsync their to see if anything on my computer may be conflicting with it but it was about same speeds. I tried different usb ports, not using a hub. Even tried different hard drives, and cables so it doesn’t seem to be a hardware related problems. The drives themselves are fairly new. I am using one thats usb3.1 & another thats usb 3.0 both WD brands.
