'export' in a shell script uses a process environment only accessible to the user. +### Package Lists +- At the moment I only use Arch and Ubuntu/Debian systems, so the package list dump only checks for these. This can be expanded as needed. +- Since I don't backup the entire system, I'd rather just do a quick dump of packages and script a reinstall as needed. +- This would be obsolete with Ansible (which I will ideally use later down the line). +### Backup Locations +- I generally do not care to backup the entire system, and only want things in /home or configs (usually in /etc) +- I use a case statement to add or remove things as needed per system. Probably not the most efficient and it's a bit ugly, but it's very clear/easy to read, debug, and modify as needed. +### Why do you copy files and directories to /home? +- I'd prefer to avoid using root when possible, especially since I don't want to backup the entire system. +- If I'm only copying /home and config files, I don't see a reason to use root, and would rather just use a local user. +- HOWEVER, there should not be a concern with using root. The networking is done by SSH and RPC, not Borg. If there is a security concern, it would be with SSH and RPC, which is pretty minimal. +### Why do you use a locally mounted remote file system instead of Borg's client/server mode? +- Mixture of laziness and old habits. Borg has made it easier to use client/server mode without mounting drives, and I just haven't kept up with the times. +- I will ideally be modifying this to use client/server mode in the future. +- Nothing particularly *wrong* with using a mount, it's just slower since every operation has to go over the network. \ No newline at end of file
