On this same topic, is there a way to have amrecover list the available
versions of a file that are currently on tape?
i.e. list the 5 versions of the file with the dates so that you can choose
the one you want?

Gordon

The normal everyday amanda incremental backup saves all the

Yes.

If the file is changed 5 times in a backup cicle it will

get backed up

5 times? if so how do I access it using amandarecover?

By specifying the date of the version you want to recover.

I've just started a job at a new company. They have an backup system with everyday copies the touched files to a disk

on a backup server and on the weekend it makes a 0 level to tape.

They say the system is not really relayable because

some times they don't find the files an want a new one.

So I will install amanda.

The problem is that they want to keep the old backup

touched files each day and zero level on the weekend.

In http://www.amanda.org/docs/topten.html#id2552255

says this is not possible.

So I will use amanda with a weekly cycle so that at

saturday everyting is backuedup.

But I still need to incremental backup the touched files since last inscremental, is it possible to force amanda to

(in its runs during week) first copy to backup server the touched files and them some others?

You can nearly mimic what they have been doing. Not

necessarily my

recommendation, but sometimes "ya gotta do what da boss

sais ya gotta do".

Think of their current backup disk as amanda's "holding disk".

Set up your amanda config to 'autoflush" the holding disk

whenever

it actually does tape.

Set up your config to not do level 0's except when forced

with amadmin.

I forget if this is "skip-full" or "incr-only".

Set up amanda to use a symbolic link to the tape device,

eg. /dev/amandatape.

This will be missing normally, so incremental backups

will collect

on the holding disk, waiting to autoflush.
Set up your daily cron job to "rm amandatape" then amdump.

Set up your weekend cronjob to amadmin force level 0's,

create the

symbolic tape device link, then do amdump, the rm amandatape.
The entire week will go to tape.

If so what will happen if a file is changed two times

in one week?

You will have a copy of each version.

During the week you can still use amrecover to get at the incrementals collecting on the holding disk.

You can use the "history" command within amrecover:

amrecover> sethost ppragin
200 Dump host set to ppragin.
amrecover> listdisk
200- List of disk for host ppragin
201- /boot

200 List of disk for host ppragin
amrecover> setdisk /boot
