Backup Central

hi.. all

Every day, I have more than 375GB to backup.

for the movement i do the backups by breaking then into different volumes. ( one volume might have maximum of 150GB of data)

below is "list volumes" out put that you can see..

Now what i am going to do is write all the backups for a day into one single volume so there is going to be 7 volumes and one single volume going to have up to 400GB of data.

Is Bacula volumes capable to handle that much of data. or is it good to have small volumes like 150GB

Is it ok to have up to 400GB in a bacula volume... on a file storage device..

will it be a problem when restoring the backups..???

Is it ok to have up to 400GB in a bacula volume... on a file storage
device..

Yes. I have some tapes (LTO2) at work with over 1 TB of data on them
however most of my 100+ tapes average around 300 GB of data since I
get about 1.5:1 compression on average depending on the job and client
since compression (hw in this case) varies depending on the fileset.

thanks john..

but..
Sorry i made a mistake in my problem... im not going to use tapes any
more... to store backups. i brought a new NAS with 7TB..

so only the copy jobs will be stored in the tapes..

my question is can Bacula handle up to 400GB of data (it may grow up till
500GB within a year) in a single volume on a file storage device.. if it is
possible i am going to store all the backups for a day in a single volume.

if not i can break it and store.. in this case i am going to store the
backups for a day in to 3 volumes. each around 150GB

can you pls tel me what is efficient.. sorry if my English is not clear


For file based volumes I recommend much smaller volumes. However
bacula will handle 400GB disk volumes.

John

Not a problem whatsoever. I have several almost-1TB volumes on my
Bacula file storage.
