UNIX for Dummies Questions & Answers

Hello All,

I just inherent a new server with RedHat AS4 and ACL file system. I'm new to ACL and was trying to dump the system for backup and got errors that the ACL inodes would not be backed up. I have tried different command for backup such as star pax but found that there is a limitation of file size. I use to just do a dump of the partition to a file. I would like to know how everyone is doing backup that keeps the ACL tables intact for system recovery.

Thanks All

Actually, most of the backup utilities, even big ones such as HP's Omniback do not support ACLs. Probably too much info will have to be maintained per file. I have a suggestion in this case: use the command on your system that will give out ACL info for files and redirect it to a file in the same directory. Then go ahead with the backup. This will also backup the file that has the ACL info. In the event of a restore, that file can be used to reassign ACLs to files.

In case of HP, the lsacl command can be used to provide input to chacl (which sets ACLs on files). I am sure that your filesystem will provide something similar.

Hi there
