I use /NOALIAS whenever I do a /IMAGE

But the problem is on the restore operation.
When restoring directories with aliases, I have to manually do SET
FILE/ENTER after the restore.

$ back sys$sysdevice:[sys*...]*.*.*/noalias
$1$dga64:[temp]s.bck/sav/igno=int
erl
%BACKUP-W-ADNOTSAVED, alias directory SYS$SYSDEVICE:[SYS0]SYSCOMMON.DIR;1
and it
s directory tree not saved
%BACKUP-W-ADNOTSAVED, alias directory SYS$SYSDEVICE:[SYS1]SYSCOMMON.DIR;1
and it
s directory tree not saved
%BACKUP-W-AFNOTSAVED, alias file SYS$SYSDEVICE:[SYS0]SYSCOMMON.DIR;1 was not
sav
ed
%BACKUP-W-AFNOTSAVED, alias file SYS$SYSDEVICE:[SYS1]SYSCOMMON.DIR;1 was not
sav
ed
$
$ back $1$dga64:[temp]s.bck/sav $1$dga64:[temp...]*.*.*/alias
$ dir $1$dga64:[temp.sys0]SYSCOMMON.dir
%DIRECT-W-NOFILES, no files found

This is very cumbersome.

If, otoh, I use the /ALIAS qualifier in the backup, the restore will create
multiple copies of the files, which is somewhat worse.

Anyone knows how to do a good restore with file aliases? I can recreate them
manually because I know what they are on my system, but it's far from being
ideal.

Thanks
