rsync - recursive and preserving permissions
Had a case where i need to sync up /hana/data dn /hana/log to a whole new disk..
i used rsync, but f-up the permission part..
so here's a note to myself
rsync -rlptgoDHAX <source-dir> <target-dir>
-p, --perms preserve permissions
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
-H, --hard-links Preserve hard links-A, --acls This option causes rsync to update the destination ACLs to be the same as the source ACLs. The option also implies --perms. The source and destination systems must have compatible ACL entries for this option to work properly. See the --fake-super option for a way to backup and restore ACLs that are not compatible. -X, --xattrs This option causes rsync to update the destination extended attributes to be the same as the source ones. For systems that support extended-attribute namespaces, a copy being done by a super-user copies all namespaces except system.*. A normal user only copies the user.* namespace. To be able to backup and restore non-user namespaces as a normal user, see the --fake-super option.//alak
