The table `videos` grows a lot and needs the most storage. You can clean it up using following commands:
|
|
|
|
```bash
|
|
|
|
$ sudo -i -u postgres
|
2019-01-24 18:11:14 +00:00
|
|
|
$ psql invidious -c "DELETE FROM nonces * WHERE expire < current_timestamp"
|
2019-01-24 17:49:21 +00:00
|
|
|
$ psql invidious -c "TRUNCATE TABLE videos"
|
|
|
|
$ exit
|
2019-01-24 18:11:14 +00:00
|
|
|
```
|
|
|
|
|
|
|
|
For regular maintenance you should add a cronjob for these commands
|
|
|
|
```bash
|
2019-01-25 18:38:56 +00:00
|
|
|
@weekly psql invidious -c "DELETE FROM nonces * WHERE expire < current_timestamp" > /dev/null
|
|
|
|
@weekly psql invidious -c "TRUNCATE TABLE videos" > /dev/null
|

```
