HI all

no matter how many times I read the page on volume management I cant get my head around it.

I have 3 servers with 4tb of storage each. I cant seem to figure out how to stop baroes simply eating all the space up. Here are my pools..

Pool {

Name = Differential

Pool Type = Backup

Recycle = yes # Bareos can automatically recycle Volumes

AutoPrune = yes # Prune expired volumes

Volume Retention = 15 days # How long should the Differential Backups be kept? (#09)

Maximum Volume Bytes = 10G # Limit Volume size to something reasonable

Maximum Volumes = =100 # Limit number of Volumes in Pool

Label Format = "Differential-" # Volumes will be labeled "Differential-<volume-id>"

}

Pool {

Name = Full

Pool Type = Backup

Recycle = yes # Bareos can automatically recycle Volumes

AutoPrune = yes # Prune expired volumes

Volume Retention = 30 days # How long should the Full Backups be kept? (#06)

Maximum Volume Bytes = 50G # Limit Volume size to something reasonable

Maximum Volumes = 50 # Limit number of Volumes in Pool

Label Format = "Full-" # Volumes will be labeled "Full-<volume-id>"

}

Pool {

Name = Incremental

Pool Type = Backup

Recycle = yes # Bareos can automatically recycle Volumes

AutoPrune = yes # Prune expired volumes

Volume Retention = 15 days # How long should the Incremental Backups be kept? (#12)

Maximum Volume Bytes = 1G # Limit Volume size to something reasonable

Maximum Volumes = 200 # Limit number of Volumes in Pool

Label Format = "Incremental-" # Volumes will be labeled "Incremental-<volume-id>"

}

why does it just keep eating space?

There are files in there that date back to Dec

-rw-r----- 1 bareos bareos 4225951421 Dec 3 13:46 Full-0010

why have these not been recycled?

Why do I have files older than 30 days?

so confused

Bareos will keep provisioning volumes trying to avoid blowing away data until it absolutely have to. The retentions are much more about when they become a candidate for purge.

I personally have a script I run after some jobs so they actually get pruned when ready and truncated/recycled:

#!/bin/bash
for x in `echo "list volumes pool=AI-Consolidated" | bconsole | grep -v "list volumes" | grep AI-Consolid | awk -F\| '{print $3}'`
do
echo "prune volume=$x yes"
done | bconsole

# actaully free up disk space
echo "truncate volstatus=Purged pool=AI-Consolidated yes" \
| bconsole

This gets ran once a day and wipes out all the volumes that are past retention but not being marked used/purged.

This works well for me, and I also have a tape drive (copy jobs) and in the tape world it makes a lot more sense.

Hi,

not sure if this is just a typo in your mail or if you did a copy-past
from your real file (this message will not respond to your question,
but...) you have 2 times a == in your Differential pool

Maybe Job Retention and File Retention, could help, like in this example:

Pool {
Name = Differential
Pool Type = Backup
Recycle = yes # Bareos can automatically
recycle Volumes
AutoPrune = yes # Prune expired volumes

Volume Retention = 60 days # How long should the

Differential Backups be kept? (#09)

Job Retention = 59 days
File Retention = 58 days
Maximum Volume Bytes = 300G # Limit Volume size to something

reasonable
Maximum Volumes = 200 # Limit number of Volumes in Pool

Label Format = "Differential-" # Volumes will be labeled
"Differential-<volume-id>"
}

Pool {
Name = Full
Pool Type = Backup
Recycle = yes # Bareos can automatically
recycle Volumes

Maximum Volume Bytes = 500 G # Limit Volume size to something
reasonable
Maximum Volumes = 300 # Limit number of Volumes in Pool

Label Format = "Full-" # Volumes will be labeled
"Full-<volume-id>"

AutoPrune = yes # Prune expired volumes

Volume Retention = 180 days # How long should the Full
Backups be kept? (#06)
Job Retention = 179 days
File Retention = 178 days

}
Pool {
Name = Incremental
Pool Type = Backup
Recycle = yes # Bareos can automatically
recycle Volumes
AutoPrune = yes # Prune expired volumes

Volume Retention = 28 days # How long should the Incremental
Backups be kept? (#12)
Job Retention = 27 days
File Retention = 26 days
Maximum Volume Bytes = 100G # Limit Volume size to
something reasonable
Maximum Volumes = 400 # Limit number of Volumes in Pool

Label Format = "Incremental-" # Volumes will be labeled
"Incremental-<volume-id>"
}
