Version: xtrabackup version 8.0.30-23 based on MySQL server 8.0.30 Linux (x86\_64) (revision id: 873b467185c)

I have **Full** backup files: compress formate is LZ4.  
Ex:  
xtrabackup\_checkpoints.00000000000000000001  
xtrabackup\_checkpoints.00000000000000000000  
xtrabackup\_info.lz4.00000000000000000000  
xtrabackup\_info.lz4.00000000000000000001  
xtrabackup\_tablespaces.lz4.00000000000000000000  
xtrabackup\_tablespaces.lz4.00000000000000000001

- I am trying to Restore backup files so i running following command  
`xtrabackup --decompress --parallel=16 --target-dir=/home/backup/pxccluster-2023-07-12-02\:00\:01-full --remove-original`  
**Output**  
`[Note] [MY-011825] [Xtrabackup] completed OK!`  
**Error**  
Still LZ4 file not converted in target-dir  
Not sure what is the issue.  
I have installed: LZ4 package using

```auto
$ sudo apt install lz4
version: ***LZ4 command line interface 64-bits v1.9.3, by Yann Collet***

```

Hi @chethan4046

Do you also have the uncompressed files in there?  
I mean, do you have something like this:

```auto
xtrabackup_info
xtrabackup_info.lz4.00000000000000000000
xtrabackup_info.lz4.00000000000000000001

```

Or just the compressed files?

Also, could you please share the command you used to create the backup?

Best,  
Mauricio.
