Relax-and-Recover (rear) Issue Template¶

Please fill in the following items before submitting a new issue:

rear version (/usr/sbin/rear -V): Relax-and-Recover 1.17.2 / Git
OS version (cat /etc/rear/os.conf or lsb_release -a): RHEL 6.7
rear configuration files (cat /etc/rear/site.conf or cat /etc/rear/local.conf):
OUTPUT=ISO
GRUB_RESCUE=1
Brief description of the issue

Issue - I was trying to clone a system via Rear. I used some other system's rescue image. When I reach to rescue shell it asks me to restore all the data to /mnt/local. How do I do that ?
I want to use TSM for restore. I cannot do unless there is a TSM Client installed on it.
How can I do this? Any Idea?
I cant install anything now, as it is in rescue mode.

Is there any other way to do it ?
Is there a Procedure to make Rear work with TSM ?

Thank You
Akshay Saraf

On the source system you should also add BACKUP=TSM to the local.conf file and make sure you have a full backup made by TSM. Use the newly created rear rescue image to boot on the target system and you are ready to go.

And see usr/share/rear/conf/default.conf
in particular see therein the "BACKUP=TSM stuff".

FYI
why you got that

Please start the restore process on your backup host.
Make sure that you restore the data into /mnt/local
instead of '/' because the hard disks of the recovered
system are mounted there.

text see also usr/share/rear/conf/default.conf that contains

# default backup and output targets
BACKUP=REQUESTRESTORE
...
# BACKUP=REQUESTRESTORE stuff
##
# This mode stops the restore after formatting and mounting the filesystems and expects
# the backup data to appear by miracle (e.g. you doing something).
...
# The text to display in order to prompt the user to restore the data
REQUESTRESTORE_TEXT="Please start the restore process on your backup host.
Make sure that you restore the data into $TARGET_FS_ROOT (by default '/mnt/local')
instead of '/' because the hard disks of the recovered system are mounted there.
"

Thank s lot for your prompt response.
How will I restore from TSM when the System is in Rescue Mode ?
Can TSM Push Backup ?
Won't it need TSM Client installed that time ?

Thank You

When booted from the rescue image just type 'rear -v recover' and the
restore will be invoked via TSM - pure magic, no?

Sorry, you have to install the TSM Client on the rescue system.
Here are my /etc/rear/local.conf part for TSM-Restore for an Redhat 6.x System:

BACKUP=TSM
PROGS_TSM=(dsmc)
TSM_RESULT_FILE_PATH=/opt/tivoli/tsm/rear
TSM_RESULT_SAVE=n

Now create a new rescue image and an working TSM Cllint wil be there.

Thanks a Lot Joeri-MS. Your configuration worked Perfectly. Could you please tell me what does TSM_RESULT_FILE_PATH Mean ?

Also when I run "rear -v mkbackup" after this configuration. It creates a rear ISO file in /var/lib/rear/output directory and also in /opt/tivoli/tsm/rear directory. What is the difference between these 2 files ?

gdha commented at 2016-05-24 07:37:¶

@Joeri-MS conf/default.conf:PROGS_TSM=(dsmc) so there is no need to add it to the local.conf file.
@akshaysarraf2016

onf/default.conf:# where to copy the resulting files to and save them with TSM
conf/default.conf:TSM_RESULT_FILE_PATH=/opt/tivoli/tsm/rear

And, you are right currently you will find the exact ISO images on your system (see issue #734 which is not implemented yet).

No further comments since more than 4 month
indicate that the issue is sufficiently answered.
I am closing it now.
If needed it can be reopened.
