The problem is that "restore"/"backup" file format has no "table of contents", so basically "restore" has to read the whole file to generate it. The limiting factor is the speed of the tape (this is probably the case with the "backup" too).
What you can do is: instead of piping the file list directly into "backup" create a file first. Then write this file first at the rmt-device, only then use the same list as input to "backup". Write to the "/dev/rmtN.1" instead of "/dev/rmtN", this is the drive without "rewind on exit", so your "table of contents" will be the first entry on the cartridge. You can restore this single file to get/search a list of files backed up in this session.
Backup (schematic)
Search (=restore toc only)
Restore (schematic, skip first entry, then restore normally)
I hope this helps.

I'm pulling a 1MB file from tape using tar. It's a 300GB DLT tape and it does have a lot of files on it because it's go the entire OS and Oracle RMAN files and 3000 table exports, but it's taking 2-3 hours to pull this file off of it. Is this type of performance what I should expect?

Hi,
We replaced one of our tape drives (attached to a SPARC Server) with an LTO5 one (external, attached vi SAS). Manually we check (using tar) that the OS can write data to the Tape Drive, however, the application backup is failing.
Since the application takes its own backup, the apps team... (0 Replies)

bootcdbackup - create a bootable offline backup of a unix system
SYNOPSIS
bootcdbackup [-i] [-v] [-s] [-c <config directory>] [-url <url] [-nomount] [-2diskconf <file>] <dev> <name> <builddir>
DESCRIPTION
bootcdbackup creates a offline backup from a installed system. You need a running bootcd to boot the system with. This CD/DVD is booted on
the system and bootcdbackup creates a bootable CD/DVD with the bootcd kernel and the backup disk as tar-file.
To restore or clone the system, boot the CD/DVD image and install it with bootcd2disk -c <name> on the system.
bootcdbackup can try to discover the disk partition by searching for fstab on the given partition. A other way to backup the partition ta-
ble is the program bootcdmk2diskconf which creates a configuration file on a running system.
OPTIONS -i The bootcdbackup runs in interactive mode and you can run each function manually. This option is useful for debugging.
-v The option "-v" (verbose) adds messages on running.
-s This option can be used to disable interactive questions and to try to ignore errors.
-c <config directory>
The configuration directory which includes the file "bootcdbackup.conf", default is "/etc/bootcd".
-url <url>
If bootcdbackup is slow on your system (because of a slow CD/DVD drive or the HP ILO virtual CD interface), you can use an image server
to get the image from.
bootcdbackup use the SWAP partition of your upcoming system as temporary space and copy the image from the configured image server to
this partition and use it as image. The image server url is configured with this option.
-nomount
The target disk should not be mounted and no search for fstab is done.
--cpio
Normally as backup tool star will be used if selinux files have to be backed up and cpio will be used if not. With this option the
usage of cpio can be forced.
--star
Normally as backup tool star will be used if selinux files have to be backed up and cpio will be used if not. With this option the
usage of star can be forced.
-2diskconf <file>
The parameter configures a bootcd2disk.conf for the restore of the system done by bootcd2disk. The configuration file can be created
with the command bootcdmk2diskconf.
<dev>
Configures the device where bootcdbackup finds the file "fstab" and discover the configuration for the restore.
<name>
The name of the backup (no blanks!) is used on the creation time and to restore the backup with bootcd2disk -c <name>.
<builddir>
Builddir is an directory on the backup system where bootcdbackup build the backup CD/DVD. Space for the CD/DVD image, for compression
and the data is needed!
All other configuration has to be done in the config files.
