Hi there,
there are quite a number of errors on the bug tracker related to smeserver-affa, and the code is obviously unmaintained. The original author seems to depreciate the use of SME, see e.g. http://affa.sourceforge.net/ or http://wiki.nikoforge.org/How_to_move_Affa_from_SME-Server_to_a_Server_with_Affa_V3 .
Affa on SME is still useful and saved one of my SME installations a month ago using this HowTo http://wiki.contribs.org/Moving_SME_to_new_Hardware . I was just able to retrieve a backup before the HDD of my SME 8.1 failed completely :grin:
I am currently evaluating new concepts to regularly and automatically backup my SMEs. Affa would be a great candidate, but what about the prominent warning here http://wiki.contribs.org/Affa "Warning: This code is deprecated and unmaintained. smeserver-affa has a waiting list of 32 open bugs . And a lot of unpredictable bugs are associated or related with the use of Affa after restoration or rise, such as missing groups, service crash, CGI errors" ?
Pros I see:
- certain success stories like mine, see above
- ease of use
- Affa 3 probably portable to SME, runs on CentOS
Cons from my perspective:
- Affa 2 for SME is unmaintained
- author seems to have moved away from SME
- not too much discussions on http://sourceforge.net/p/affa/discussion/ : is Affa 3 unmaintained as well?
What kind of solution for automated backups would you recommend? Would you still favor smeserver-affa 2.0.0?
Regards, turandot

test affa 3 -> http://bugs.contribs.org/show_bug.cgi?id=7633

Wow... I wasn't aware about this bug tracker item.
I will thoroughly go through it in the next days. May be I can contribute by testing etc.
Thanks a lot,

Just wanted to let you know that Affa 3 works on SME 8.1 as expected in general, see http://bugs.contribs.org/show_bug.cgi?id=7633 , as well as using an SME server to backup another SME server. See http://forums.contribs.org/index.php/topic,51040.0.html (http://forums.contribs.org/index.php/topic,51040.0.html) for more details how I did that.
Thanks,

What is wrong with using the built in backup (to workstation) in server manager to either a locally connected USB drive or a network share (workstation or NAS).
I realise it does not have the same feature set as Affa (eg rise feature, & ability to quickly rise a backup server to production status).
The built in backup using dar is fully supported by sme core developers.
For an alternative that is used by sme server professional support personnel, & can backup locally or remotely via ssh, see
http://wiki.contribs.org/Rdiff-backup

Then you ought to convince the developer to bring out his baby to the light and set up a wiki page on this topic. If it is not yet possible, then you should help arnaud to finish that contrib (test, development, ....)

Nothing at all, except one thing: manual intervention is required.

Right, this is very attractive. I have used it in the past, e.g. to migrate to new hardware. Workstation backups should work perfectly for that.

I simply wasn't aware of Rdiff-backup up to now. I have used Affa since a long time... Keep also in mind that I started this thread asking for recommendations :-)
A 'must have' for me was to have a second machine making fully automated remote backups each and every day without any manual intervention over a VPN network connection, using hard links for rolling backups. Affa is capable for all that. Rdiff-backup probably too...

Absolutely. I have been in touch with Arnaud directly, but I guess he is currently out on holidays. (So I will be in a few days.) I have tested Affa 3 quite a bit, and I posted my experiences and detailed steps in the bug tracker. Unfortunately I am not capable to build RPM packages, so this needs to be left e.g. to Arnaud. I would be happy to transfer my steps from the bug tracker e.g. into the Wiki. I have never done this before in the SME forum (I have used Wikis elsewhere), but why not start with a HowTo on Affa 3!?

Go but in the header let a warning for test purpose, backups are a sensitive topic.
If you lack of experience on how to write with wiki, either you can edit other pages to see how it works (what I did sometime ago) or you can start and other will come to help.
Alone you can walk faster, but numerous we can go much far than alone....

As I said: I will be out on holidays in a few days, so please be patient with me.
Please let me know how to create an account for the Contribs Wiki (I couldn't find a 'create account' button), as well as how to create a new Wiki page.
Would you recommend to modify the existing description http://wiki.contribs.org/Affa , or should I start with a new one? There are substantial differences between earlier versions and Affa 3, therefore I would vote for a new one...
Thanks, turandot

see http://wiki.contribs.org/Help:Contents#How_to_get_a_wiki_account.3F
Yes you should start to create a new page.
On the main page of the wiki you have a wiki search box (below one of google) simply search affa3 and if nothing exists then it proposes to create the page affa3.
Here you have the wiki help http://wiki.contribs.org/Help:Contents
Take your laptop and an internet connexion in holidays :)
Keep us (me) in touch if you have issue on the granting of wiki edit permissions.

stephdl,
I have now requested edit rights for the Wiki.
I will indeed take my laptop with me in the vacation, but you may (or may not!?) know that Corsica is quite attractive for outdoor activities 8-)

Obviously if the challenge is to walk on the GR20, please let your laptop at home, it will be too heavy for your ballad.
Good holidays !!!

Personally I prefer one Contrib article per contrib name, so editing the existing article & adding everything about the new smeserver-affa3 there would be best (in my opinion).
You could say it supersedes the older information & is (most) applicable to sme9.0
RequestedDeletion suggested a good way to deal with versioning, by use of tabbed pages, otherwise just add everything at the start as the latest & greatest for sme 9.0
I am also in favour of keeping old & superseded information & wiki articles etc, as they are a source of good ideas & procedures, even if dated & no longer exactly applicable, rather than deleting old stuff.
