Restore folder from backup (kolab 2.04)

[Jacques Hylkema]

Hello,

I have problems restoring a folder of one of my users, which he
accidentally deleted.

I tried the following:
- Restored the folder from a backup using scp
- The folder in question is:
/kolab/var/imapd/spool/domain/intronics.nl/user/j^m^dekker/Leveranciers/R--S
- Changed the owner and group of the folder and all subfolders and files
to kolab-r / kolab-r
- su - kolab-r
- /kolab/bin/cyrreconstruct -r -f
user/j^m^dekker/Leveranciers/*@intronics.nl

The output of this displayed all folders within Leveranciers, except the
R--S folder. I did not see any "discover" line and the folder could not
be seen in Thunderbird
Then I deleted all cyrus.* files from the R--S folder, including
sub-folders, and ran the cyrreconstruct again, with the same result.

I have the following configuration:

Kolab2 Groupware Server Version
2.0.4

Kolab2 Groupware Server Component Versions

Their is no discover because all the folder are already in the mailbox.db

can you try a

user/j^m^dekker/Leveranciers/*@intronics.nl

Have you tried reconstructing the top level folder? I.e.:

/kolab/bin/cyrreconstruct -r -f user/j^m^dekker/Leveranciers at intronics.nl

As far as I remember this is necessary to tell Cyrus about the new folder - it
will not recognise it automatically.

Also, I strongly recommend to re-calculate your quotas after you have restored
your folders, otherwise they can get quite out of whack. Cyrus does not do
this for you if you add/delete mail "manually" to/from the spool. The command
is: su - kolab-r -c "/kolab/bin/cyrquota -f"
A word of caution: This will recalculate *all* quotas - there seems to be no
easy way to recalculate the quota for only one user. Also, if you already
have restored/deleted manually in the spool in the past, your quotas may
already be wrong. If this is the case, the recalculation can produce very
strange results. Running it more than once can help, or, if that does not
help, reconstruct the complete mailbox of any user whose quota is off, then
re-run the quota command.

This gives the following result:
user/j.m.dekker/Leveranciers at intronics.nl

If I use:

/kolab/bin/cyrreconstruct -r -f user/j^m^dekker/Leveranciers/*@intronics.nl

then I see all folders and subfolders below Leveranciers in the result.
(not Leveranciers itself) so I tried:

/kolab/bin/cyrreconstruct -r -f user/j^m^dekker/Leveranciers*@intronics.nl

which does the same as above, but does include the Leveranciers folder
itself.
However, still no sign of the R--S folder...

OK, That's good to know. In this case, the user in question has no quota
set, because his mailbox is about 6GB. I have found that setting a quota
larger than 3GB gives problems on Kolab 2.0.4.

I think I have to follow another procedure:

Create a (temporary) kolab mailserver with the latest version of kolab.
Create the user in kolab, and restore the folder to that mailserver.
reconstruct the folder on that mailserver.
Add a new account to Thunderbird for the temporary mailserver
Drag and drop the folder from the new temporary account to the original
account

Does this seem to be a good workaround to you?

Thanks for your co-operation.

Jacques

I think the folder name could be the problem.

There is a more simple solution, imapsync. It is included in debian installation.
You need just to type: aptitude -i imapsync

I used it to migrate succesfully from kolab 2.0 to kolab 2.1

Ok, in that case I would try a complete reconstruct of the user's mailbox:

su - kolab-r -c "cyrreconstruct -r -f user/j^m^dekker/*@intronics.nl"

followed by

su - kolab-r -c "cyrreconstruct -r -f user/j^m^dekker at intronics.nl"

We have had problems with this in the past, but at least under 2.1.0, most of
these reconstructions were successful.

BTW: Maybe this is a stupid question, but: You *DID* check that the folder in
question has not become unsubscribed in the mail client and is therefore not
visible?

Far too much work. Our standard procedure in case the straightforward
reconstruction of a previously existing folder does not work is this:

- Create a NEW folder in /kolab/var/imapd/spool/...../USER (i.e. in the top
level
- Copy all of the mails you want to restore into that folder
- chown -R kolab-r.kolab-r FOLDER (i.e. make certain FOLDER and all contents
belong to kolab-r)
- Restore that new folder:
su - kolab-r -c "cyrreconstruct -r -f user/USER/FOLDER at intronics.nl"
- Ask the user to subscribe to this folder, then fetch mail and transfer the
mails to wherever (s)he wants to have them.

This has always worked for us.

Thomas

Yes! You're the greatest!
When I created the directory using cyradm, and restored the

perfectly.

I would like to thank everyone for their help and time.

Thanks Jacques - and I've added my remark about the quotas to that as well.

Good point! I forgot about that.

I found a solution, use cyradm and create the folder before reconstruct it.
as user kolab-r
cyradm --user manager localhost

Duh - silly me, I clearly was not fully awake when writing my previous mail -
yes, you're absolutely right, you need to use cyadm to create the folder, not
just mkdir. We even have that written down in our own internal procedures and
I still completely forgot about that... :-/

Hello,
I have problems restoring a folder of one of my users, which he
accidentally deleted.
- Restored the folder from a backup using scp
/kolab/var/imapd/spool/domain/intronics.nl/user/j^m^dekker/Leveranciers/R--
S - Changed the owner and group of the folder and all subfolders and files
to kolab-r / kolab-r
- su - kolab-r
- /kolab/bin/cyrreconstruct -r -f
The output of this displayed all folders within Leveranciers, except the
R--S folder. I did not see any "discover" line and the folder could not
be seen in Thunderbird
Then I deleted all cyrus.* files from the R--S folder, including
sub-folders, and ran the cyrreconstruct again, with the same result.
Kolab2 Groupware Server Version
2.0.4

Hi,

I ran into the same problems a while ago, I solved it by copying the file
cyrus.header from a working folder (i. e. the Inbox) to the folder in
question, then cyrreconstruct found the folder all mail was available again,
albeit marked as unread, but i guess this is only a minor nuisance.
