Hi all,
I'm new in this domain, and on this operating system, but in my job, i have to find a way to make a disaster recovery plan for our server (sun solaris) which has the oracle database. I don't have any standby servers to be used for data replication, i only want to use CD's to put on them all the system image of solaris, to be ready incase of any failure might happens to the solaris server. don't know am i clear with my explanation ? waiting for your advise on that ...
regards,
Sam ...
Hi - I am no DR recovery expert but I would assume you need the following at least.
Assumption is that your server has disappeared off the face of the planet and you have to start from scratch
Another node - that you could restore to
Full system backups should be enough - as long as your dr site has full connectivity to the rest of your network.
I dont know much about oracle - but I would assume the full backup should cover it - maybe others could answer?
hi,
thank you for replying. actually what i need is to get the system image of sun solaris server i have, and put it on CD(s), so that they will be ready incase of any crash or failure might happens ... is there any commands in solaris for taking the system image of the whole system ? i'm trying to avoid buying anything like softwares or any package for this purpose.
thanks alot ...
The tool you�re looking for is flarcreate , and it comes with your Solaris distribution.
Flar => Flash archive
A flash archive is a snapshot of a complete system, including all installed software, users , drivers and so on.....
Example to create a full (also incremental possible) flash archive on a Solaris 9 SPARC server with compression enabled:
root@sun-test-3 # flarcreate -n full-flash -R / -c -x /net full-flash
where
-n => the name seen at installation time
full-flash => the name seen on the filesystem
-c => compress
-x => exclude directories, in example /net will be excluded
-R => your root directory, or where to start (i think / is default)
I think this is what you are looking about...
see also "man flarcreate"
You can load the flash image over the network (NFS,HTTP,FTP) in a DR situation from a file server....
OK, so I have the flar archive from the system and at the time of creation I got a couple of errors like cpio: "var/vx/isis/vea_portal" ? and these files have a sticky bit
ls -l /var/vx/isis/vea_portal
srwxr-xr-x 1 root root 0 Mar 10 14:16 /var/vx/isis/vea_portal
but besides that I do think I have a flar archive. How do I restore it somewhere and check it's authenticity now?
