Question Can tar archive files with extended attributes


Environment:
Centos 6.6 X86_64; File system:ext4

Question: Can tar archive files with extended attributes?

for example:
# chattr +a /tmp/logs/softa.log
-----a-------e- /tmp/logs/softa.log

I try to archive it by the follow
# tar --xattrs -Jpcvf /tmp/logs.tar.xz /tmp/logs

then I try to restore by the follow
# tar -Jxvf /tmp/logs.tar.xz -C /tmp/logs_b
# tar --xattrs -Jpxvf /tmp/logs.tar.xz -C /tmp/logs_a

but it didn't have +a
-------------e- /tmp/logs_a/tmp/logs/softa.log
-------------e- /tmp/logs_b/tmp/logs/softa.log

Thanks in advance

probably you need to run as root to be able to restore everything

Hi pan64

I run as root, I follow your link, but it still fails.

tar --selinux --acls --xattrs -cvf file.tar /var/www
tar -xvf file.tar

I also test facl with -acl, the acl is ok
