Mise à jour archivist

arnauld · December 5, 2019, 9:05am

Bonjour,

Merci pour la mise à jour d’Archivist.
Avant celle-ci les backups s’effectuaient bien mais n’étaient pas ‘encryptés’ :

Clean old backup files
Encrypt backups
The directory “/media/storage/archivist/encrypted_backup/” does not exist. Should it be created? (y,n) Directory not created.
Unable to locate mount point, aborting.Build: encfs version 1.9.1

Usage: encfs [options] rootDir mountPoint [-- [FUSE Mount Options]]

Common Options:
-H show optional FUSE Mount Options
-s disable multithreaded operation
-f run in foreground (don’t spawn daemon).
Error messages will be sent to stderr
instead of syslog.
-v, --verbose verbose: output encfs debug messages
-i, --idle=MINUTES Auto unmount after period of inactivity
–anykey Do not verify correct key is being used
–forcedecode decode data even if an error is detected
(for filesystems using MAC block headers)
–public act as a typical multi-user filesystem
(encfs must be run as root)
–reverse reverse encryption
–extpass=program Use external program for password prompt

Example, to mount at ~/crypt with raw storage in ~/.crypt :
encfs ~/.crypt ~/crypt

For more information, see the man page encfs(1)

Maintenant il semble que depuis la mise à jour je n’ai plus ce problème et les backups semblent bien ‘encryptés’ dans le dossier ‘encrypted_backup’. Car j’y ai bien des fichiers.

Par contre j’ai ce message :

Clean old backup files

sudo: ccrypt: command not found

Hello

Is the encryption what you asked for ?

About ccrypt, indeed, I added it to archivist but forgot to add it as a dependency to archivist_ynh. My bad, I’ll fix that right now.

arnauld · December 5, 2019, 10:55am

Hello,

Yes it is about encryption. Before the recent update my backups failed to be encrypted, but since the update the encryption process seems to be successful as the ‘encrypted_backup’ folder fills up with files. I wanted to let you know…

Maniack_Crudelis · December 5, 2019, 10:57am

Thanks for the notice then

I’ve upgraded archivist_ynh, now you should have ccrypt as a dependency.
It would be now fixed.

Let me know if it’s not.

arnauld · December 7, 2019, 8:02am

Hello,

I now have this error message:

I don’t know about that find, but the error with mount is usual if you run the script twice.
It doesn’t affect the process though, that just because the directory isn’t yet umount.

Did you get that message from the nightly backup ? Or from a manual command line ?

arnauld · December 7, 2019, 11:14am

From a nightly backup. I run a backup every night.

Maniack_Crudelis · December 7, 2019, 11:27am

Ok, that’s strange.

Could you run mount to see if the directory is still mounted, and also have a look to the directory itself. It should be empty.
If not, try to umount it.

arnauld · December 8, 2019, 4:26pm

When I run mount I obtain this:

Maniack_Crudelis · December 8, 2019, 4:48pm

As expected, the directory is still mounted.
So could you try to umount it.

arnauld · December 9, 2019, 12:15pm

Thank you for your help Maniack_Crudelis, it worked.

I unmounted the directory yesterday afternoon and the automated backup of this night completed without errors:

Clean old backup files
Delete empty directory ‘/media/storage/archivist/encrypted_backup’
Encrypt backups

Maniack_Crudelis · December 9, 2019, 12:18pm

Nice !

Check though if the directory is now unmounted, it could be an error.

arnauld · December 9, 2019, 1:59pm

Ok, so I ran:

admin@arnauld:~ $ mount | grep /media/storage/archivist/encrypted_backup > /dev/null && echo mounted || echo unmounted
mounted

It says it is mounted…

Maniack_Crudelis · December 9, 2019, 4:57pm

And when you use umount on it, there’s no specific error message or whatever else ?
The directory is supposed to unmount itself after 5 min of inactivity.

arnauld · December 9, 2019, 5:19pm

No, when I run
sudo umount /media/storage/archivist/encrypted_backup

I have no error message. My Yunohost set up is like this:

On a Pi with an attached hdd. I moved everything on the hdd except the boot part. So everything is on the hdd.

Maniack_Crudelis · December 9, 2019, 5:28pm

Hum ok.

The only thing left I can think of is to have a look to your logs. If the umount command fails, you should have something about it into your logs.

I would say syslog, but maybe another one.

arnauld · December 9, 2019, 5:52pm

Ok, thank you. I’ll have a look this week when I have time.

arnauld · December 11, 2019, 2:15pm

Ok, I’m browsing syslog.1 (for the right time and date, as syslog doesn’t record the time when cron launches archivist) but can’t find anything interesting as I don’t really know what I am supposed to look for…

Maniack_Crudelis · December 11, 2019, 3:23pm

Something about encfs, mount or more probably fuse.
It could as well be in other logs.

grep could help you find something.
