[SOLVED] Unable to restore backup piped over ssh

[FuriousGeorge]

SOLVED:

It was simply an uncompressed vma file. I did:

cat myfile.vma | qmrestore - 101
​

What follows is the original post.



================================================


On SERVER_A, I send a backup to SERVER_B like this:

vzdump 105 --stdout | ssh -p 25222 root@20ttt.ddns.net "cat - > /var/lib/vz/dump/vzdump-qemu-115-octavio.vma.gz"​

However, on the other side, I'm not able to extract the file. Whether it is a .gz or a .lzo, i get an error similar to:

TASK ERROR: command 'set -o pipefail && zcat /var/lib/vz/dump/vzdump-qemu-115-octavio.vma.gz | vma extract -v -r /var/tmp/vzdumptmp6405.fifo - /var/tmp/vzdumptmp6405' failed: got timeout
​

I've also tried renaming the file to .lzo and I've updated to the latest Proxmox. Neither helps. I'm not able to determine the type of compression used:

# file vzdump-qemu-115-octavio.vma.lzo
vzdump-qemu-115-octavio.vma.lzo: data​

... but I assume it is whatever the default is.

I can see what appears to be my <vmid>.conf file and a block device image in the file:

it seems you do not use any compression, so you use cat instead of zcat and the 'vma' extension instead of 'vma.gz'
