cannot restore LXC from LZO and GZ

[karnz]

Hello,

I cannot restore LXC from lzo backup and received this error.

extracting archive '/mnt/pve/nfs/dump/vzdump-lxc-100-2018_04_27-02_00_02.tar.lzo'
lzop: <stdin>: Checksum error
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
Logical volume "vm-101-disk-1" successfully removed
TASK ERROR: command 'tar xpf - --lzop --totals --one-file-system -p --sparse --numeric-owner --acls --xattrs '--xattrs-include=user.*' '--xattrs-include=security.capability' '--warning=no-file-ignored' '--warning=no-xattr-write' -C /var/lib/lxc/101/rootfs --skip-old-files --anchored --exclude './dev/*'' failed: exit code 2

Tried to test backup file, got checksum error

lzop -t vzdump-lxc-100-2018_04_27-02_00_02.tar.lzo
testing vzdump-lxc-100-2018_04_27-02_00_02.tar.lzo
lzop: vzdump-lxc-100-2018_04_27-02_00_02.tar.lzo: Checksum error
FAILED

Restore will be OK if backup as non-compressed .tar but failed for both .lzo & .gz

Anyone can help or guide me please?

Seems that backup file is damaged.

Thanks Dietmar, but backup process finished without error. So wondering what's wrong?

The file can also get damaged after the backup (faulty storage).

Run in to this problem when the LXC container had a snap-shot. Unfortunately backup did not give any error message. Delete snap-shots and try again.
