SID-00968: restore from backup after system crash

Status:	Answered	TWiki version:	4.1.2	Perl version:	5.8.8
Category:	CategoryInstallation	Server OS:	Ubuntu	Last update:	14 years ago

Hi, our server crashed (lost 2 drives in a raid 5

I have a newly build twiki server and would require to restore the twiki from a good full sytem backup of the old twiki.

From what I can read, I found the following, Correct me if I am wrong.

1- copy the data and pub folders keeping the permissions. 2- replace .htpasswd with the .htpasswd from the backups?

I understand copying the data and pubs, but will the .htpasswd file restore the user accounts or will the accounts need to be restored from another file or re-created manually?

thanks

Discussion and Answer

Do you restore to the same TWiki version? If so, simply restore all twiki/data and twiki/pub, it will carry over user homepages in twiki/data/Main as well as .htpasswd.

If you upgrade to a newer TWiki make sure to exclude twiki/data/TWiki, twiki/pub/TWiki, twiki/data/Main, twiki/pub/Main. Then you need to restore user homepages and other non-system pages in twiki/data/Main. You need also restore the .htpasswd.

Hi I followed your instructions, but had one difference. On my newly built Turnkey twiki VM Appliance which includes Ubuntu 8.04 and Twiki 4.1 did not have a /var/www/twiki/data folder. So I copied all of my backup /twiki/data directory to it. All my copies were done keeping all permissions. This copied my .httpasswd file which I can see all the users.

I rebooted, but nothin seems different on my twiki. Do I need to modify any files manually?

thanks

Hi, I also noticed that on my new twiki I only have the following in the Twiki folder

root@twiki:/var/www/twiki# ls

data pub

root@twiki:/var/www/twiki#

And on my backup folder for /var/www/twiki, I have

root@twiki:/usr/twiki# ls
AUTHORS TWikiHistory.html index_e.html~ styles
ActionTrackerPlugin.tgz_FILES TWikiReleaseNotes04x01.html index_f.html subdir-htaccess.txt
ActionTrackerPlugin_installer TWikiUpgradeGuide.html index_f.html~ templates
BlogAddOn.zip_FILES TagMePlugin.tgz_FILES lib test
BlogAddOn_installer TagMePlugin_installer locale tools
COPYING bin pub twiki_httpd.conf~
COPYRIGHT data pub-htaccess.txt wysiwyg.cgi~
CalendarPlugin_installer images readme.txt wysiwyg_installer.cgi
INSTALL.html index.html~ robots.txt
LICENSE index_e.html root-htaccess.txt
root@twiki:/usr/twiki#

should I be copying more than just twiki/data and twiki/pub?

thanks

Hi , I found data in /var/lib/twiki/data and /var/lib/twiki/data on this new appliance. I created a new web to see what happened. I called it marcweb. the weird thing is that it created in the /var/www/twiki/pub, where I copied my files as indicated in the restore procedure. I also ended finding it in the /var/lib/twiki/data and /var/lib/twiki/pub, but not the other webs I copied so I think that this is the path for the data in my twiki server.

I will revert back my VM snapshot and try it again using the /var/lib/twiki location.

my question is, I don't know the admin user password because the admin left the organization, can I vi the .htpasswd file and keep my admin user and copy the users from the backup .htpasswd file?

thanks

and sorry for the long posts, I am reletavely new to Twiki and must rebuild a server that was droped on my lap.

At least I have backups!!

Regards
