Backups#
| Tool | Backs up | Use |
|---|---|---|
| Timeshift (Digital Asset Managers) | the system (installed Animux) | take a snapshot before big updates; roll back if something breaks |
| a copy to an external disk | your projects | drag ~/Projects to the disk in the file manager, or use the command below |
| Borg, rsnapshot, rclone (terminal) | projects, automatically, also to the cloud | for advanced users |
rsync -a --info=progress2 ~/Projects/ /media/$USER/BACKUP/Projects/
Timeshift does not back up your Home folder by default. That is what the project copy is for.
Disks#
- Disks (System → Disks): see all disks, check their health (SMART Data), format USB sticks, create disk images.
- GParted (System → GParted): resize and create partitions.
Danger
Both can erase data. Check the disk name and size twice before you click Format or Apply.
Burning discs: K3b#
DVD Authoring → Backup → K3b. New Data Project for a backup DVD, New Video DVD Project if you already have DVD video files, Burn Image to write an ISO to disc.
Watching the system#
| Tool | Shows |
|---|---|
Task Manager (System) or htop |
which programs use processor and memory; end a frozen program |
btop, glances |
a colourful overview of everything |
nvidia-smi (NVIDIA driver installed) |
graphics card use |
| Psensor | temperatures. Long renders heat the computer; check that fans work |
df -h, Disk Usage Analyzer |
free disk space |
Virtual machines and containers#
Animux includes QEMU, Virtual Machine Manager (System → Virtual Machine Manager), Docker and Podman for running other systems or packaged services (for example a web server for a render farm dashboard). They are for advanced users.
Remote access#
The SSH server is installed and enabled on installed systems. From another computer: ssh your-login@animux-computer. Useful to start renders on a render node. Change the default live password if a live system is connected to a network you do not trust.
Security#
ufw (firewall), fail2ban, rkhunter and lynis are included. On r16 (_21) the fail2ban service reports an error at start-up (fixed in r16.1, see Troubleshooting); it does no harm.
