Your opinion on my Hetzner rsync backup to Storage Box setup
I bought a dedicated server and also a storage box from Hetzner. And I have setup the storage box in the way I leave below. Can you please see and give me your opinion? Is this a good setup or should I use a different method?
a) Mount Storage Box to server /mnt/storagebox using CIFS as describes at:
https://docs.hetzner.com/robot/storage-box/access/access-samba-cifs since I think is the best option for reliability and speed.
b) I just need to backup 1 folder. So I install rsync and setup the below cronjob:
05 3 * * * /usr/bin/rsync -a --delete /folder1 /mnt/storagebox/folder1
c) Activate on Hetzner Storage box panel, automatic daily snapshots, keeping the last 5 snapshots.
In resume with this setup, my objective is to always have a daily snapshot backup of the last 5 days. Since snapshot access folder is disable, even if my server is hacked, the hacker will not be able to gain access and delete my snapshot backups.
P.S: Server is running Ubuntu 20.04
Any opinion or advice is appreciated. Thanks!
