complexity: O(1) to create the new key and additional O(N*M) to reconstruct the serialized
  value, where N is the number of Redis objects composing the value and M their average
  size. For small string values the time complexity is thus O(1)+O(1*M) where M is
  small, so simply O(1). However for sorted set values the complexity is O(N*M*log(N))
  because inserting values into sorted sets is O(log(N)).

summary: Creates a key from the serialized representation of a value.
syntax_fmt: "RESTORE key ttl serialized-value [REPLACE] [ABSTTL]\n  [IDLETIME\_seconds]\
  \ [FREQ\_frequency]"
title: RESTORE
---
Create a key associated with a value that is obtained by deserializing the
provided serialized value (obtained via [`DUMP`]({{< relref "/commands/dump" >}})).

If `ttl` is 0 the key is created without any expire, otherwise the specified
expire time (in milliseconds) is set.

If the `ABSTTL` modifier was used, `ttl` should represent an absolute
[Unix timestamp][hewowu] (in milliseconds) in which the key will expire.

[hewowu]: http://en.wikipedia.org/wiki/Unix_time

For eviction purposes, you may use the `IDLETIME` or `FREQ` modifiers. See
[`OBJECT`]({{< relref "/commands/object" >}}) for more information.

`RESTORE` will return a "Target key name is busy" error when `key` already
exists unless you use the `REPLACE` modifier.

`RESTORE` checks the RDB version and data checksum.
If they don't match an error is returned.

## Examples

```
redis> DEL mykey
0
redis> RESTORE mykey 0 "\n\x17\x17\x00\x00\x00\x12\x00\x00\x00\x03\x00\
                        x00\xc0\x01\x00\x04\xc0\x02\x00\x04\xc0\x03\x00\
                        xff\x04\x00u#<\xc0;.\xe9\xdd"
OK
redis> TYPE mykey
list
redis> LRANGE mykey 0 -1
1) "1"
2) "2"
3) "3"
```
