How to recover files from Ignite-UX archives

Ignite-UX archives are just compressed tar archives created with the "pax" command. The archives can be read with the "tar" and "pax" commands. The tar capacity to extract single files or directories can be used to recover single files or directories from an Ignite-UX archive.

If you need to extract the file(s) to a relative path, check Extracting archives to relative directories using pax

Net recovery archives

Ignite-UX net recovery archives are store on the /var/opt/ignite/recovery/archives/<hostname>/<timestamp>.gz Is required to uncompress the file prior to extract the file using "tar", but this can be acomplish using a piped gunzip. Normally, you may mount the NFS shared directory or use a "remsh" session to complete the task.

# mount -F nfs /var/opt/ignite/recovery/archives/<hostname> /mnt
# gunzip < /mnt/"<timestamp>" | tar xvf - <file_or_directory>

or

 # remsh <hostname> -n "( cd /var/opt/ignite/recovery/archives/<hostname>; gunzip < <timestamp>.gz )" | tar xvf - <file_or_directory>

Tape recovery archives

Extracting files from a tape can take a long time, especially when archives are large or tape technology is relative slow.

HP 9000

The HP 9000 PA-RISC platform copy the archive in the second section of the tape. So is necesary to forward the tape to section 1.

# mt -f /dev/rmt/#m rew
# mt -f /dev/rmt/#mn fsf 1
# tar -xvf /dev/rmt/#m <file_or_directory>

Integrity

The Integrity platform copy the archive in the 22th section of the tape. So is necesary to forward the tape to section 22.

# mt -f /dev/rmt/#mn rew
# mt -f /dev/rmt/#mn fsf 22
# tar -xvf /dev/rmt/#mn <file_or_directory>

Extracting files from a tape can take a long time, especially when archives are large or tape technology is relative slow.

HP 9000

The HP 9000 PA-RISC platform the tar archive in the 2nd section of the tape. So is necesary to forward the tape to section 1.

# mt -f /dev/rmt/#m rew
# mt -f /dev/rmt/#mn fsf 1
# tar -tvf /dev/rmt/#m

Integrity

The Integrity platform the tar archive is in the 23th section of the tape. So is necesary to forward the tape to section 22.

# mt -f /dev/rmt/#mn rew
# mt -f /dev/rmt/#mn fsf 22
# tar -tvf /dev/rmt/#mn
