Backup restoration in different directory.


I’m making incremental backups using xtrabackup.
My problem is that I can’t find how do I have to do to perform the restoration.

I’d like to restore (prepare) my backup into a different directory where the backup is.
Else I think that when I apply my incremental backups will overwrite full backup information.

At the moment I’m copying full backup directory in a tmp one and then I prepare the incremental backups.
I have 31 GB of backup and to copy it is a long process.

As I understand, if I apply incremental backups over a full backup I’ll get the full backup after the incremental period. But I’ll lose my previous full backup, isn’t it?
I need to keep my full backup as it was before.

Anyone knows how could I prepare a incremental backup pointing a different directory?
I can’t find any information about it.
I’ve tried using different options as --datadir, --tmpdir even --targetdir (that I don’t rememeber where found it) but my tmp directory continues being empty.


Hello Marcos, have you read this following page for further information about the process?
[url]Incremental Backups with innobackupex


I’ve seen this page, but maybe I don’t undetstand the working.

As I can see I could apply-log over BASE-DIR (that I understand is where the full backup is) and then I apply incremental logs over this BASE-DIR. Then I’ll have a “full backup” up to the time of the incremental one in BASE-DIR. As I see then I’ll had lost my first full backup, isn’t it?
I can’t lose the base full backup.

That I need is to be able to keep recovering information any moment of the past.
My incremental backup are done each two hours, and maybe I could need 12:00PM information and later to recover 8.00AM info.

I don’t know if is possible to do it by a easy way :confused:

Thanks again!


You need to make a copy of your full backup if you want to keep it. Copy it to a ‘staging’ area where you will apply incrementals to it and keep the original in some safe place.
