Totaling up clone size before clone
Happy almost New Year!
Does anyone know how I can see the total clone size before the clone is sent to tape?
I have a situation where I might be using a second tape in my clone job but I'm not sure when. I would like to see it coming before the clone job starts so I know roughly how long the clone will run.
Sometimes our Networker server is dominated by a clone job (only one tape drive) so I like to estimate these things.
No Events found!

Clone saveset size will be same as the original Saveset size.
That means if the saveset size is 1GB, then clone saveset will also be 1GB size.

Hi, thanks for your help. Also, how can I sum all of the save-sets up so that I know how big they are when all added together? Right now, I have to run a report to add them all up but I'd kind of like to see the totals IN the interface.

Hi,
Have a look in the 'Reports' section of the NMC. The 'NetWorker Backup statistics' section contains a list of reports that you can customise to give you the amount of data that correpsonds to a set of criteria (for example, the amount of data backed up for a certain client between two dates).

Yes I do see that feature now... I'm just used to seeing totals and sums on the screen
e.g. The saveset column's contents (MB,GB,TB) would be summed (all of them together) and show up by default under header "Total:"
I look for interface elements like this in order to find a method of planning disk requirements. Currently, when I start to run out of space on my servers... I have no condrete method of estimating my space requirements in the future...

You can also script reports by using mminfo to give you the size of ssid and sum it up with bc, perl or whatever you like.

If you are using automatic cloning then it will the same as the original backup. However in case you are doing volume cloning then there is a change. You need to identify all the volumes to be cloned, then find the savesets which start on these volumes and get there total size.
For instance suppose you have a tape which has got 4 savesets, 1 complete (cb), 2 (mb), (1 hb), then you will need to find the volumes, on which saveset 1 spans, because this is the only saveset which will be cloned. The required space will be same as the saveset size.
You can get more information, from the networker admin guide. The thumb rule is that, in case of volume cloning all the savesets starting on the cloned volume will be cloned. You may need more/less volume compared to the source volume.
