Beta Branch Centmin Mod Backups - Attic Deduplication Backups

Looking for some help to install it and test it as it seems the debian instructions for dependencies are not the same as on Centos 64Bit :

for example:

Code:

[root@free ~]# yum install libacl1 liblz4-1
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: ftp.plusline.de
* extras: ftp.plusline.de
* updates: mirror.imt-systems.com
No package libacl1 available.
No package liblz4-1 available.
Error: Nothing to do

 

Attic causes data corruption on large repositories

Comparison of Attic vs Bup vs Obnam

 

For the borg install you give this your post:

After running the pip install virtualenv I got this:

Code:

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm not a programmer - so can I just executed that statement before I go on with the rest of those pip install commands?

 

It was - thanks:

Code:

[root@sarah tools]# pip install --upgrade pip

So - after install of newer python on 09beta1 - I use the @eva2000 borg guide for install.. After that I created a new virtual disk for storing of local backup while testing it. The goal is for sure - remote storage like nfs or perhaps something like sshfs. Got the disk mounted - execute borg backup on my XF install.. Added -v --stats as parameters and got this for you:

Code:

[root@sarah tools]# borg-env/bin/borg create -v --stats --compression lz4 /backupstore/borgstorage::mt-backup-`date +%Y-%m-%d` /home/nginx/domains/yourdomin/public

So all is fine for now.. So @eva2000 - again, thanks for your guide, that got me started..

 

I'm playing with Attic mount and I got this

fuse: device not found, try 'modprobe fuse' first
attic: Exiting with failure status due to previous errors

I tried modprobe fuse but still gets the same error when mounting

 

The last update from me about this borg backup. I got fuse-sshfs installed - make a share on another server - did sshfs to that and mounted it 'here' on this server.. Same files, same server but remote storages by sshfs:

Code:

[root@sarah tools]# borg-env/bin/borg create -v --stats --compression lz4 /backupstore/borgremote/borgstorage::mt-backup-`date +%Y-%m-%d` /home/nginx/domains/yourdomain/public

So the local storages duration against remote storage duration is:

Local -Duration: 57.93 seconds
Remote - Duration: 1 minutes 9.14 seconds

Not much lost in time - allright - its only 2 GB and without DB. So now comes a cron with mysqldump first and then backup of files.

 

Yes OpenVZ. Oh snap.

 

Once again, I want to plug Obnam as its simple install on Centos and very reliable history on repo data... its production ready (not a beta quality software)... Dev used to work at Canonical... Obnam - backup program

Would love to see this integrated with C.M.M. Some discussion here: https://community.centminmod.com/threads/anyone-tried-rsnapshot-alternative-obnam.5688

Easy install..

Code:

yum install obnam fuse python-fuse

 

this is offtopic since this is an attic thread but the feedback that I've seen regarding Obnam is that it's too slow in creating and restoring. Take this for example

obnam forget being really slow (4 hours to delete a single generation)

@ethanpil

 

So does Attic create corrupted backups on huge files or not?

 

I don't think you can get the right answer to that in here .. Maybe take a look on the maillist archive - [attic] archives
