+# Granular Backups
+
+The `BACKUP` command also works with granular backups of specific tables. Example AWS commands for backing up a specific table are listed below. GCP and Azure commands are similar to the ones explained above, except that they need to be customized to backup specific tables.
+
+### Take a Granular Backup
+**Full Backup**
+```sql
+BACKUP TABLE data TO S3('https://testchbackups.s3.amazonaws.com/backups/<uuid>', '<key id>', '<key
+secret>')
+```
+
+**Incremental Backup**
+```sql
+BACKUP TABLE data TO S3('https://testchbackups.s3.amazonaws.com/backups/my_incremental/', '<key id>', '<key
+secret>') SETTINGS base_backup = S3('https://testchbackups.s3.amazonaws.com/backups/<base-backup-uuid>', '<key id>', '<key
+secret>')
+```
+
+### Restore from Granular Backup
+```sql
+RESTORE TABLE data AS data3 FROM
+S3('https://testchbackups.s3.amazonaws.com/backups/my_incremental', '<key id>', '<key secret>')
+```
+
+### Backup and Restore all service data
+**Backup**
+```sql
+BACKUP TABLE system.settings_profiles, TABLE system.row_policies, TABLE system.quotas, TABLE system.functions, ALL EXCEPT DATABASES INFORMATION_SCHEMA,information_schema,system TO S3('https://testchbackups.s3.amazonaws.com/backups/', '<key id>', '<key secret>')
+```
+
+**Restore**
+```sql
+RESTORE ALL FROM S3('https://testchbackups.s3.amazonaws.com/backups/', '<key id>', '<key secret>')
+```
