Solaris

Hi Solaris Specialists,

I need to carry out a disaster recovery backup using Solaris 10 x86 Flash Archive (flarcreate - http://docs.oracle.com/cd/E18752_01/html/821-1912/flashoverview-2.html) on a critical productin server where maintenance downtime is reduced to a minimal. Only 2 filesystems exists on 2 mirrored 350GB disks which is made up of root “/” (< 5.0GB) while the application including MySQL data is located in /export/home (>100GB). As a result, I would appreciate your input on exactly what is being backed up using flarcreate and how long will it take?

Past fssnap & ufsdump full backup of /export/home (applications & DB down) took around 4 hrs to remote server via NFS. I am hoping that it would only backup system configuration files in root “/” filesystem leaving /export/home for commercial backup application such as Symmantec Netbackup, even though it is still not clear what is the integrity of MySQL database being backup while in active production mode.

I would like to change the hostname & IP address (/etc/inet/hosts & /etc/inet/ipnodes) of the source archive (/FLAR_recovery/newsystem_recovery.flar - pg 65) prior to installing it on to the cloned Solaris 10 x86 target system.

Many thanks in advance,

George

See the flarcreate man page. As far as I recall, the "normal file list" , mentioned in the man page, is the list of files visible in the file system hierarchy i.e. all mounted filesystems.

Thank you to both fpmurphy & DukeNuke2,

By booting Solaris 10 x86 to single-user mode will mount the root "/" filesystem only in most case, where I have successfully completed a few flash archives backups using flarcreate which took a good 45min (~6.8GB). The restore of application (/export/home) filesystem can be done from the regular Symmantec netbackup software to the DR system at a later time.

Thanks for your inputs,

George

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)



Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Hi All,

Could someone give me examples of the restriction on using flash archive on all hardware platforms, but particularly x86 between the master and clone systems? In other word, do they have to be identical or only limited to the same vendor. E.g. HP compare to DELL?

Thanks a lot,

George
