# Data Backup
|
||||
|
||||
While [replication](table_engines/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](https://github.com/yandex/ClickHouse/blob/v18.14.18-stable/dbms/programs/server/config.xml#L322-L330). However, these safeguards don't cover all possible cases and can be circumvented.

# Резервное копирование данных

|

[Репликация](table_engines/replication.md) обеспечивает защиту от аппаратных сбоев, но не защищает от человеческих ошибок: случайного удаления данных, удаления не той таблицы, которую надо было, или таблицы на не том кластере, а также программных ошибок, которые приводят к неправильной обработке данных или их повреждению. Во многих случаях подобные ошибки влияют на все реплики. ClickHouse имеет встроенные средства защиты для предотвращения некоторых типов ошибок — например, по умолчанию [не получится удалить таблицы *MergeTree, содержащие более 50 Гб данных, одной командой](https://github.com/yandex/ClickHouse/blob/v18.14.18-stable/dbms/programs/server/config.xml#L322-L330). Однако эти средства защиты не охватывают все возможные случаи и могут быть обойдены.
