# Replicating SQLite
|
|
|
|
Next to your regular [backup methods](../admin/backup_and_restore.md), you might want to set up replication for disaster recovery to another path or external host.
|
|
|
|
For this to work properly, SQLite needs the journal mode to be configured in `WAL` mode, with synchronous mode set to `NORMAL`. This is the default configuration for GoToSocial.
|
|
|
|
You can check your settings in the configuration file. The journal mode is set in `db-sqlite-journal-mode` and the synchronous mode in `db-sqlite-synchronous`.
|
|
|
|
## Litestream on Linux
|
|
|
|
A relatively light, and fast way to set up replication with SQLite is by using [Litestream](https://litestream.io). It can be configured very easily and supports different backends like file based replication, S3 compatible storage and many other setups.
|
|
|
|
You can then install the prebuilt package by either the deb file on Linux, or building it from source on other distributions.
|
|
|
|
Using a .deb package on Linux:
|
|
|
|
Navigate to the [releases page](https://github.com/benbjohnson/litestream/releases/latest), and download the latest release (make sure to select the appropiate platform for the wget command below).
|
|
|
|
|
|
```bash
|
|
wget https://github.com/benbjohnson/litestream/releases/download/v0.3.13/litestream-v0.3.13-linux-amd64.deb
|
|
sudo dpkg -i litestream-*.deb
|
|
```
|
|
|
|
## Configuring Litestream
|
|
|
|
Configuration is done by editing the configuration file. It's located in /etc/litestream.yml.
|
|
|
|
### Configuring file based replication
|
|
|
|
```yaml
|
|
dbs:
|
|
- path: /gotosocial/sqlite.db
|
|
- path: /backup/sqlite.db
|
|
```
|
|
|
|
### Configuring S3 based replication
|
|
|
|
Set up a bucket for replication, and make sure to set it to be private.
|
|
Make sure to replace the example `access-key-id` and `secret-access-key` with the proper values from your dashboard.
|
|
|
|
```yaml
|
|
access-key-id: AKIAJSIE27KKMHXI3BJQ
|
|
secret-access-key: 5bEYu26084qjSFyclM/f2pz4gviSfoOg+mFwBH39
|
|
|
|
dbs:
|
|
- path: /gotosocial/sqlite.db
|
|
- url: s3://my.bucket.com/db
|
|
|
|
```
|
|
|
|
When using a S3 compatible storage provider you will need to set an endpoint.
|
|
For example for minio this can be done with the following configuration.
|
|
|
|
```yaml
|
|
access-key-id: miniouser
|
|
secret-access-key: miniopassword
|
|
|
|
dbs:
|
|
- path: /gotosocial/sqlite.db
|
|
- type: s3
|
|
bucket: mybucket
|
|
path: sqlite.db
|
|
endpoint: minio:9000
|
|
```
|
|
|
|
## Enabling replication
|
|
|
|
You can enable replication on Linux by enabling the Litestream service.
|
|
|
|
```bash
|
|
sudo systemctl enable litestream
|
|
sudo systemctl start litestream
|
|
```
|
|
|
|
Check if it's running properly using `sudo journalctl -u litestream -f`.
|
|
|
|
If you need to change the configuration file, restart Litestream:
|
|
|
|
```bash
|
|
sudo systemctl restart litestream
|
|
```
|
|
|
|
### Recovering from the configured backend
|
|
|
|
You can pull down a recovery file from the stored backend with the following simple command.
|
|
|
|
```bash
|
|
sudo litestream restore
|
|
```
|
|
|
|
If you have configured multiple files to be backupped, or have multiple replicas, specify what you want to do.
|
|
|
|
For filebased replication:
|
|
|
|
```bash
|
|
sudo litestream restore -o /gotosocial/sqlite.db /backup/sqlite.db
|
|
```
|
|
|
|
For s3 based replication:
|
|
|
|
```bash
|
|
sudo litestream restore -o /gotosocial/sqlite.db s3://bucketname/db
|
|
```
