Hello, I have a file, mybackuplist, with a list of paths:
/home/yod/somefile
/home/yod/Documents/someotherfile
etc...
I use it to make a tarball with the following command
tar -cpvf backup.tar -T mybackuplist
I noticed that the file permissions are indeed saved but the directories permissions are lost,
so someotherfile maintains the correct permissions
but
/home/yod/Documents
/home/yod
/home
lose the permissions

Now, if in the file list, I specificy the directory instead of the file, the directory and the file permission are saved correctly.
So if in mybackuplist I specify
/home/yod/Documents/
The permissions of
/home/yod/Documents/
/home/yod/Documents/someotherfile
are saved correctly

I wonder if there is a way to specify the file and not lose the parents directories permissions.
Im using tar but I wouldn't mind using something else

Maybe take a look at rsync.

https://linux.die.net/man/1/rsync

Thanks for the suggest but the problem with rsync is that I can't save the backup in a cloud, do you know if there is a way?
My plan was: make a shell/python script that creates a tarball and upload it in google drive through rclone and run the script periodically with a cronjob or systemd/Timers

Can you clarify your plans a little more? Any normal GNU/Linux-based VPS is going to have full Rsync support, so I would second the recommendation to use the Rsync protocol. However, if privacy or confidentiality is a factor then you will have to encrypt prior to uploading and that complicates things.

I don't have a server, I just want to backup some file of my OS. I can rsync to another hard disk but I prefer in a cloud to make it more available.
So when I format my OS, I just need to download it and extract. Thats what I was thinking.

Server is another name for "cloud". Can you please specify which one or ones you are planning for?

Most are rather weak in their offerings. However, as mentioned a plain old VPS will give you a lot for your money. Or you can use Rsync to save to a larger USB drive.

Yea I know that a cloud is a server, I thought you were saying I had to backup a server, sorry my english is bad.
Well, a VPS is a good choice but I don't want to pay for such a small thing. I have to backup mostly config files. Its a overkill

Use rsync to create a local backup directory, then copy that to the cloud...

You mean copy the directory in the cloud instead of a tarball? Don't you lose permissions anyway?
