Dear,
I have some misunderstand related to Backup Module in NS. I have set NFS server on NS and shared 1 directory Eg. - ( /backup ) and i have set Incremental Backup + Full Backup on Sunday.
but when i see in /backup everyday its creating a lot of backup files so we are not able to understand
which is our authentic backup.
SO please Help us to understand, How it takes Backup which backup is authentic and why it is creating everytime new backup files.

root@mc # ll /backup

It’s the same backup but it’s split into different files, in your example your backup is duplicity-full.20151129T170114Z full backup executed on 29 Nov

Dear alefattorini,

Thanks for your valuable reply.

but i don’t understand, if i create 1 full backup and it creates 200 Files for backup. So at the time of restoration we have to select 200 files for restore.
what kind of backup philosophy is this ?
i have done full backup then it created 200 tar backup files, then i set incremental backup and set sunday for full backup with 1 week retention policy but we are not able to identify which backup is Full or which backup is incremented.

So please give us an idea about this in brief and tell whether we can restore this backup ?

Thanks
Hitesh

Why select? Check this
http://docs.nethserver.org/it/latest/backup.html#file-e-directory

restore a file

restore-file / /var/lib/nethserver/vmail/test

Restore the system

restore-data

Very simple :smile: and you can use web interface too

Dear Alefattorini,

200 Tar files backup is like this "duplicity-full.20151129T170114Z.vol998.difftar.gz"
so now how i ll restore this, and also not identified which one is incremental backup.

Is there any other way to take backup like Eg. - Rsync

and also tell us how to take backup of owncloud ?

Thanks
Hitesh

The backup is split in chunks of fixed size; this is how duplicity works: duplicity: Features

I guess/hope you meant:

http://docs.nethserver.org/en/latest/backup.html#file-e-directory

or do you expect Hitesh to read the italian page? :smiley:

Yep that’s the proper link!
