Storage size when restorting .tar.gz container

[Sharky04]

When restoring a .tar.gz backup of a container the correct storage and ram size is restored too.

Where is that information saved? Inside the .tar.gz backup?

It is inside the vma.lzo file

to verify
lzop -d <filename>.vma.lzo
vma list <filename>.vma

For containers, it is stored inside the tar file. The first file of the tar archive contains the VM config.

What is the filename?

 

[ermanishchawla]

What is the filename?

Go to /var/lib/vz/dump

you will find file name with extension vma.lzo

I mean the filename of the VM config file inside the tar archive where the ram and storage size is stored.

I know dump files are in /var/lib/vz/dump

'./etc/vzdump/pct.conf'
(you can check the contents of a tar.lzo archive with `tar --lzop -tf $tar.lzo`)

I hope this helps!

Thanks. Since the UI doesn't allow to size down containers I plan to do a backup, change the rootfs size inside pct.conf, then restore with smaller size.

That did work. I have sized down a container from 40 to 8 GB. It would be neat if during restore the size of the container could be configured.

it does (on the CLI/API level, but not exposed on the GUI). you can actually totally reconfigure the container when restoring, including splitting up mountpoints differently than they were before
