phil 6b9bd80fa8 ## 3.2.0
### Added
- File logging to `/var/log/ha-backup.log`. Each line has a full date and time,
  and the file is appended to on every run.
- New `LOG_FILE` setting in `home_assistant_backup.conf`. Set it to a custom
  path, or to `"none"` to disable file logging.
- `ssh`/`scp` error output is also written to the log file.
- Deletions of old local backups are now logged.

### Changed
- All console messages now go through the same logger, so remote cleanup,
  notification failures and config validation errors appear in the log too.
- If the log file can't be opened (for example, no write permission to
  `/var/log`), a warning is printed and the backup continues without file logging.
- The terminal progress bar stays on the console only and is not written to the log.

# ha-backup v3.1.1
Go port of `home_assistant_backup.sh`. Uses the same `home_assistant_backup.conf`.
## Build
CGO_ENABLED=0 go build -trimpath -ldflags="-s -w" -o ha-backup .
Override the version at build time if needed:
CGO_ENABLED=0 go build -trimpath -ldflags="-s -w -X main.version=3.1.2" -o ha-backup .
Check the version:
./ha-backup -version
Cross-compile examples:
GOOS=linux GOARCH=amd64 go build -o ha-backup-linux-amd64 .
GOOS=linux GOARCH=arm64 go build -o ha-backup-linux-arm64 . # Raspberry Pi / ARM NAS
## Logging
ha-backup writes a log to `/var/log/ha-backup.log` by default. Each line is timestamped, and the file is appended to on every run. The same output is still printed to the console.
### Create the log file
Writing to `/var/log` requires elevated permissions, so create the file once and give ownership to the user that runs the backup. Replace `backupuser` with that user (use `root` if you run it as root):
If you'd rather do it in steps:
```
sudo touch /var/log/ha-backup.log
sudo chown backupuser:backupuser /var/log/ha-backup.log
sudo chmod 640 /var/log/ha-backup.log
```
If the log file can't be opened, ha-backup prints a warning and continues the backup without file logging.
### Change or disable the log location
Set `LOG_FILE` in `home_assistant_backup.conf`:
```bash
LOG_FILE="/var/log/ha-backup.log" # default
LOG_FILE="/home/backupuser/ha-backup.log" # custom path
LOG_FILE="none" # disable file logging
```
## Run
./ha-backup # looks for home_assistant_backup.conf next to the binary, then in cwd
./ha-backup -config /path/to.conf
Requires `ssh` and `scp` on the machine running it. `jq` and `yq` are no longer needed.
