Subvol is a simple tool for BTRFS subvolumes and snapshots.

• subvol help
• subvol list
• subvol create SUBVOLUME
• subvol delete SUBVOLUME
• subvol snapshot help
• subvol snapshot list SUBVOLUME
• subvol snapshot create [SUBVOLUME|all] [HINT]
• subvol snapshot delete SUBVOLUME [SNAPSHOT|NUMBER|RANGE]
• subvol snapshot rollback SUBVOLUME [SNAPSHOT|NUMBER]
• subvol struct help
• subvol struct check
• subvol struct init
• subvol free

The subvolumes and snapshots are organized in the folowing directories:

• /subvol
• /subvol/subvolumes
• /subvol/snapshots

Note that by default the structure is on the file system root. You can change the variableSUBVOL_BASE_DIR to use another directory.

1. Copy the scriptsubvol to/usr/local/bin/

sudo cp'subvol''/usr/local/bin/';sudo chmod +x'/usr/local/bin/subvol';

2. Initiate thesubvol structure on/subvol directory

subvol struct init

Execute these steps to enable automatic snapshots on boot.

sudo cp'subvol-snapshot-auto.service''/etc/systemd/system/'

2. Enable the service script:

sudo systemctlenable subvol-snapshot-auto.service
