using hp-ux 10.20 backup command or other

I need to backup a system. Is backup command
a simple option to use. New site does not
have backup server. They will use 4mm dds2
tape drive for now. Or is there another
way to backup partitions other than vg00
which I have done make_recovery tape for that.

Hi:

You have 'fbackup' and 'frecover' along with 'tar', 'cpio' and 'pax' on 10.20.

I would suggest using 'fbackup'. See the manpages for more information.

Re: using hp-ux 10.20 backup command or other

Just saw that(fbackup). So if I want
to restore all or just one file. I can
do that with "frecover" ?

What about "dump" and "restore" that I
see in man pages?

Re: using hp-ux 10.20 backup command or other

fbackup is the best choice. Unlike cpio, tar, dump, etc, there is an index of all the files at the beginning of the tape and fbackup supports multiple tapes for a single backup that won't fit. fbackup is much faster than any of the classic backup tools, but be sure you use this config file for your DDS tape:

blocksperrecord 4096
records 64
checkpointfreq 4096
readerprocesses 6
maxretries 5
retrylimit 5000000
maxvoluses 200
filesperfsm 2000

Here are some example commands for fbackup/frecover:

fbackup -i / -v -c config-file -f /dev/rmt/0m

Display the tape header with dates:
frecover -V - -f /dev/rmt/0m

Display the table of contents:
frecover -I - -f /dev/rmt/0m

Hi (again):

Absolutely, yes. BOth 'fbackup' and 'frecover' use a "graph" file to list the (i)ncluded files and/or directories along with any (e)xcluded ones.

When recovering a file or files, you also have the option of recovering to your current working directory.

Re: using hp-ux 10.20 backup command or other

I'm reading through the man pages.
How do I do an interactive selective
file restore before I blow something up?

Re: using hp-ux 10.20 backup command or other

I usedt his for backup:

fbackup -0i /smacdsk -f /dev/rmt/0m

And did Bill's commands to verify.

Re: using hp-ux 10.20 backup command or other

Hi (again):

There isn't an interactive restore per se. You can use the tools to create disk-resident archives, too. The graph file lets you selectively recover as well as backup. Consider this:

# cp /etc/hosts /tmp/hosts

# fbackup -vf /var/tmp/myarchive -i /tmp

# frecover -xvof /var/tmp/myarchive -i /tmp/hosts

...restores only the 'hosts' file

Regards!

The interactive interface for fbackup is sam. Just run sam and select Backup and Recovery.
