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
$ 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:

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.
