# To run clang-tidy from CMake, build ClickHouse with -DENABLE_CLANG_TIDY=1. To show all warnings, it is
# recommended to pass "-k0" to Ninja.
# Enable all checks + disale selected checks. Feel free to remove disabled checks from below list if
# a) the new check is not controversial (this includes many checks in readability-* and google-*) or
# b) too noisy (checks with > 100 new warnings are considered noisy, this includes e.g. cppcoreguidelines-*).
# TODO Let clang-tidy check headers in further directories

# MaterializedPostgreSQL
Creates ClickHouse table with an initial data dump of PostgreSQL table and starts replication process, i.e. executes background job to apply new changes as they happen on PostgreSQL table in the remote PostgreSQL database.
If more than one table is required, it is highly recommended to use the [MaterializedPostgreSQL](../../../engines/database-engines/materialized-postgresql.md) database engine instead of the table engine and use the `materialized_postgresql_tables_list` setting, which specifies the tables to be replicated (will also be possible to add database `schema`). It will be much better in terms of CPU, fewer connections and fewer replication slots inside the remote PostgreSQL database.

# Data Backup
# Data backup and restore
While [replication](../engines/table-engines/mergetree-family/replication.md) provides protection from hardware failures, it does not protect against human errors: accidental deletion of data, deletion of the wrong table or a table on the wrong cluster, and software bugs that result in incorrect data processing or data corruption. In many cases mistakes like these will affect all replicas. ClickHouse has built-in safeguards to prevent some types of mistakes — for example, by default [you can’t just drop tables with a MergeTree-like engine containing more than 50 Gb of data](server-configuration-parameters/settings.md#max-table-size-to-drop). However, these safeguards do not cover all possible cases and can be circumvented.
@ -16,21 +16,181 @@ Each company has different resources available and business requirements, so the
Keep in mind that if you backed something up and never tried to restore it, chances are that restore will not work properly when you actually need it (or at least it will take longer than business can tolerate). So whatever backup approach you choose, make sure to automate the restore process as well, and practice it on a spare ClickHouse cluster regularly.
:::
## Duplicating Source Data Somewhere Else {#duplicating-source-data-somewhere-else}
## Configure a backup destination
In the examples below you will see the backup destination specified like `Disk('backups', '1.zip')`. To prepare the destination add a file to `/etc/clickhouse-server/config.d/backup_disk.xml` specifying the backup destination. For example, this file defines disk named `backups` and then adds that disk to the **backups > allowed_disk** list:
```xml
<clickhouse>
<storage_configuration>
<disks>
<!--highlight-next-line -->
<backups>
<type>local</type>
<path>/backups/</path>
</backups>
</disks>
</storage_configuration>
<!--highlight-start -->
<backups>
<allowed_disk>backups</allowed_disk>
<allowed_path>/backups/</allowed_path>
</backups>
<!--highlight-end -->
</clickhouse>
```
## Parameters
Backups can be either full or incremental, and can include tables (including materialized views, projections, and dictionaries), and databases. Backups can be synchronous (default) or asynchronous. They can be compressed. Backups can be password protected.
The BACKUP and RESTORE statements take a list of DATABASE and TABLE names, a destination (or source), options and settings:
- The destination for the backup, or the source for the restore. This is based on the disk defined earlier. For example `Disk('backups', 'filename.zip')`
- ASYNC: backup or restore asynchronously
- PARTITIONS: a list of partitions to restore
- SETTINGS:
- [`compression_method`](en/sql-reference/statements/create/table/#column-compression-codecs) and compression_level
- `password` for the file on disk
- `base_backup`: the destination of the previous backup of this source. For example, `Disk('backups', '1.zip')`
## Usage examples
Backup and then restore a table:
```
BACKUP TABLE test.table TO Disk('backups', '1.zip')
```
Corresponding restore:
```
RESTORE TABLE test.table FROM Disk('backups', '1.zip')
```
:::note
The above RESTORE would fail if the table `test.table` contains data, you would have to drop the table in order to test the RESTORE, or use the setting `allow_non_empty_tables=true`:
```
RESTORE TABLE test.table FROM Disk('backups', '1.zip')
SETTINGS allow_non_empty_tables=true
```
:::
Tables can be restored, or backed up, with new names:
```
RESTORE TABLE test.table AS test.table2 FROM Disk('backups', '1.zip')
```
```
BACKUP TABLE test.table3 AS test.table4 TO Disk('backups', '2.zip')
```
## Incremental backups
Incremental backups can be taken by specifying the `base_backup`.
:::note
Incremental backups depend on the base backup. The base backup must be kept available in order to be able to restore from an incremental backup.
:::
Incrementally store new data. The setting `base_backup` causes data since a previous backup to `Disk('backups', 'd.zip')` to be stored to `Disk('backups', 'incremental-a.zip')`:
```
BACKUP TABLE test.table TO Disk('backups', 'incremental-a.zip')
SETTINGS base_backup = Disk('backups', 'd.zip')
```
Restore all data from the incremental backup and the base_backup into a new table `test.table2`:
```
RESTORE TABLE test.table AS test.table2
FROM Disk('backups', 'incremental-a.zip');
```
## Assign a password to the backup
Backups written to disk can have a password applied to the file:
```
BACKUP TABLE test.table
TO Disk('backups', 'password-protected.zip')
SETTINGS password='qwerty'
```
Restore:
```
RESTORE TABLE test.table
FROM Disk('backups', 'password-protected.zip')
SETTINGS password='qwerty'
```
## Compression settings
If you would like to specify the compression method or level:
```
BACKUP TABLE test.table
TO Disk('backups', 'filename.zip')
SETTINGS compression_method='lzma', compression_level=3
```
## Restore specific partitions
If specific partitions associated with a table need to be restored these can be specified. To restore partitions 1 and 4 from backup:
```
RESTORE TABLE test.table PARTITIONS '2', '3'
FROM Disk('backups', 'filename.zip')
```
## Check the status of backups
The backup command returns an `id` and `status`, and that `id` can be used to get the status of the backup. This is very useful to check the progress of long ASYNC backups. The example below shows a failure that happened when trying to overwrite an existing backup file:
```sql
BACKUP TABLE helloworld.my_first_table TO Disk('backups', '1.zip') ASYNC
```
```response

## Alternatives
ClickHouse stores data on disk, and there are many ways to backup disks. These are some alternatives that have been used in the past, and that may fit in well in your environment.
### Duplicating Source Data Somewhere Else {#duplicating-source-data-somewhere-else}
Often data that is ingested into ClickHouse is delivered through some sort of persistent queue, such as [Apache Kafka](https://kafka.apache.org). In this case it is possible to configure an additional set of subscribers that will read the same data stream while it is being written to ClickHouse and store it in cold storage somewhere. Most companies already have some default recommended cold storage, which could be an object store or a distributed filesystem like [HDFS](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html).
## Filesystem Snapshots {#filesystem-snapshots}
### Filesystem Snapshots {#filesystem-snapshots}
Some local filesystems provide snapshot functionality (for example, [ZFS](https://en.wikipedia.org/wiki/ZFS)), but they might not be the best choice for serving live queries. A possible solution is to create additional replicas with this kind of filesystem and exclude them from the [Distributed](../engines/table-engines/special/distributed.md) tables that are used for `SELECT` queries. Snapshots on such replicas will be out of reach of any queries that modify data. As a bonus, these replicas might have special hardware configurations with more disks attached per server, which would be cost-effective.
## clickhouse-copier {#clickhouse-copier}
### clickhouse-copier {#clickhouse-copier}
[clickhouse-copier](../operations/utilities/clickhouse-copier.md) is a versatile tool that was initially created to re-shard petabyte-sized tables. It can also be used for backup and restore purposes because it reliably copies data between ClickHouse tables and clusters.
For smaller volumes of data, a simple `INSERT INTO ... SELECT ...` to remote tables might work as well.
## Manipulations with Parts {#manipulations-with-parts}
### Manipulations with Parts {#manipulations-with-parts}
ClickHouse allows using the `ALTER TABLE ... FREEZE PARTITION ...` query to create a local copy of table partitions. This is implemented using hardlinks to the `/var/lib/clickhouse/shadow/` folder, so it usually does not consume extra disk space for old data. The created copies of files are not handled by ClickHouse server, so you can just leave them there: you will have a simple backup that does not require any additional external system, but it will still be prone to hardware issues. For this reason, it’s better to remotely copy them to another location and then remove the local copies. Distributed filesystems and object stores are still a good options for this, but normal attached file servers with a large enough capacity might work as well (in this case the transfer will occur via the network filesystem or maybe [rsync](https://en.wikipedia.org/wiki/Rsync)).
Data can be restored from backup using the `ALTER TABLE ... ATTACH PARTITION ...`

In this case, only connections with trusted certificates can be established. Connections with untrusted certificates will be rejected. Thus, certificate validation allows to uniquely authenticate an incoming connection. `Common Name` field of the certificate is used to identify connected user. This allows to associate multiple certificates with the same user. Additionally, reissuing and revoking of the certificates does not affect the ClickHouse configuration.

# External Disks for Storing Data
Data, processed in ClickHouse, is usually stored in the local file system — on the same machine with the ClickHouse server. That requires large-capacity disks, which can be expensive enough. To avoid that you can store the data remotely — on [Amazon S3](https://aws.amazon.com/s3/) disks or in the Hadoop Distributed File System ([HDFS](https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html)).
To work with data stored on `Amazon S3` disks use [S3](../engines/table-engines/integrations/s3.md) table engine, and to work with data in the Hadoop Distributed File System — [HDFS](../engines/table-engines/integrations/hdfs.md) table engine.

The level of the hierarchy is called `resolution` and can receive a value from `0` till `15`, where `0` is the `base` level with the largest and coarsest cells.

## mapApply
**Syntax**
```sql
mapApply(func, map)
```
**Parameters**
- `func` - [Lamda function](../../sql-reference/functions/index.md#higher-order-functions---operator-and-lambdaparams-expr-function).
- `map` — [Map](../../sql-reference/data-types/map.md).
**Returned value**
- Returns a map obtained from the original map by application of `func(map1[i], …, mapN[i])` for each element.
**Example**
Query:
```sql
SELECT mapApply((k, v) -> (k, v * 10), _map) AS r
FROM
(
SELECT map('key1', number, 'key2', number * 2) AS _map

- `map` — [Map](../../sql-reference/data-types/map.md).
**Returned value**
- Returns a map containing only the elements in `map` for which `func(map1[i], …, mapN[i])` returns something other than 0.
**Example**
Query:
```sql
SELECT mapFilter((k, v) -> ((v % 2) = 0), _map) AS r
