# Run a named instance of backrest with its own data directory and ports.
|
|
# Multiple instances can run side-by-side for testing sync, multihost, etc.

# Usage: ./run-named.sh <name> [backend-port] [vite-port]
|
|
#
|
|
# Examples:
|
|
# ./run-named.sh alice # backend :9901, vite :5181
|
|
# ./run-named.sh bob # backend :9902, vite :5182
|
|
# ./run-named.sh alice 9910 5190 # explicit ports
|
|
