Server backup with HubiC

Well, I just ordered a HubiC 10TB plan so I must try to utilize it so that I did not waste my money :-). Hubic is a cloud storage service which provides 10TB for 5€ monthly. In this tutorial I will summarize the methods to do Linux server backup with HubiC. This will assume that you are using CentOS 6.5.

1. First, we need to install dependencies

   [bash]yum install gcc make fuse-devel curl-devel libxml2-devel openssl-devel json-c-devel[/bash]

2. Then, download and install HubiCFUSE:

   [bash]https://github.com/TurboGit/hubicfuse/archive/master.zip
   unzip master.zip
   cd hubicfuse-master
   [/bash]

3. Install and configure it (be noted to add the export statement to avoid the error ‘Unable to find libjson. Please make sure library and header files are installed.’):

   [bash]export PKG_CONFIG_PATH=/lib64/pkgconfig/
   ./configure
   make
   make install[/bash]

4. Create a new apps in HubiC Developer web interface. Be sure to use http://localhost/ for Redirection domain.
5. Generate Token by running hubic_token inside the downloaded directory

   [bash]./hubic_token
   client_id (the app’s id): api_hubic_YOUR_APPS_API
   client_secret (the app’s secret): YOUR_APPS_CLIENT_SECRECT
   redirect_uri (declared at app’s creation): https://localhost/

   For the scope -what you authorize your app to do-, enter characters as suggested
   in parenthesis, or just hit return if you don’t need the item authorized.
   Get account usage (r): r
   Get all published links in one call (r): r
   Get OpenStack credentials, eg. access to your files (r): r
   Send activation email (w): w
   Add new/Get/Delete published link (wrd): wrd

   user_login (the e-mail you used to subscribe): [email protected]
   user_pwd (your hubiC’s main password):

   Success!

   # Here is what your app needs to connect to hubiC:
   client_id=api_hubic_YOUR_APPS_API
   client_secret=YOUR_APPS_CLIENT_SECRECT
   refresh_token=YOUR_NEW_GENERATED_TOKEN_PASTE_IT_TO_$HOME/.hubicfuse[/bash]

6. Paste client_id, client_secrect, refresh_token to your $HOME/.hubicfuse file
7. Mount hubic to your server:

   [bash]mkdir /mnt/hubic
   hubicfuse /mnt/hubic -o noauto_cache,sync_read,allow_other[/bash]

8. Add the mount point to /etc/fstab:

   [bash]hubicfuse /mnt/hubic fuse user,noauto 0 0[/bash]

9. Run rsync with –no-times directive to avoid “failed to set times” error:

   [bash]rsync -uptorgvlHaz /home/ /mnt/hubic/backup/home –no-times[/bash]

10. Finally, set your crontab to run the rsync for a specific period and you are done 🙂

TroubleShooting

1. If you face the error of connection “cannot access /mnt/hubic: Transport endpoint is not connected”, just unmount and remount the hubic

   [bash]umount -l /mnt/hubic
   hubicfuse /mnt/hubic -o noauto_cache,sync_read,allow_other[/bash]
