Irix5.3 full system Backup HELP.

Post by Greg Gladston » Sat, 07 Mar 1998 04:00:00



I have an Indigo2 who's system disk I've been succesfully backing up to
DAT using the 'Backup' command under Irix 5.3.

In the verbose output I noticed a bru error- something to the effect of
'lost file <somename>, name (or path?) too long' and it goes on to list
a path that is shortened with a // somewhere in the name.

How do I get around this? I need to be able to do a full system backup
including these files with really long pathnames that bru doesn't seem
to be able to handle.

Is there another method for doing a system backup that will leave me
with a tape that can be restored onto a clean HD if nead be?

thanks for any help,
greg

By using cpio, or shorter paths.  More than likely, the omitted
files are symlinks for desktop icons in users home dirs, or some
of the installed software (tooltalk was the most likely one in 5.3,
if I remember right).

Another way to handle it is to gather the long names up, and
either copy them to another directory with a shorter name, or
cd further down in the directory tree before backing them up.

1. Help: Full System Backup

Well....as I explore more into the system, I am beginning to see more
complications. Here is the break down

SGI ONYX Reality Engine 2 running IRIX6.2
2 hard drive, the main one has efs volume (this is where root is)
then the second one mounted to this one( I think) has xfs volume.

Ok...I did a bru backup for the efs volume. And it terminates
succesfully. I have not checked the validity of the backup....is there a
way to do such (high confidence check..I need to make sure this is the
real thing..not some flakey backup).

Then next come the xfs volume HD....I can do xfsdump I assume? If I do
that, I will have a set of backup for just that HD. Then I can use the
backup and dump the data to the HD incase anything gets messed up. I
hope it works....

Does this process sound right? Any suggestion will be welcomed....Much
thanks in advance.

Sincerely

Surya Shandy
