 media management
Greetings,
We are currently evaluating CommVault and one simple aspect I haven't
yet understood; is media management based around predefined pools of
fixed size (give-or-take scratch pools) like in Networker, or
'dynamic' pools with periodic media reclamation (like TSM)?
What would be the most important concepts to look up for us to use
tape at a high utilization rate?
Thanks,
Eugene

Thanks Jerome,
What happens to a tape that was 100% full, as retention period are
reached, and it is suddenly only 50% capacity? Is there a process to
copy that data to a new tape and return the original tape to scratch?

This is probably my very #1 thing of what I feel netbackup does better than commvault. You can recompile tapes. Selective copy is a poor substitute for this. It seems like such a simple concept that they refuse to implement. I have screamed this until hoarse at everyone who would listen.
I have 6 major storage policies (3 incremental) with the only difference being how they interact with disk. I have done as much schedule and policy optimizing one can do and I still end up with half full tapes. Netbackup just lets you copy backups to new tapes, and then delete the old ones. I miss it.
Enough of my ranting. If the backups on your half full tapes are full backups, you can use selective backup to move them...again, horrible substitute, but that's all there is.

Perhaps you could make a copy of the still valid data, but it'd bo much more expedient to just let the entire tape expire when all the data has aged. There's other ways to keep like data on a tape, like starting fulls on new media, or using incremental storage policies so incrementals and fulls are never on the same media. Another method is to only apply extended retention to a secondary copy of the data.

Here is a list of what I have done to help get more tape utilization (though half-full tapes are still an issue).
As Jerome said, I use Incremental Storage Policies. My incrementals are 30 days, 1 cycle, and no extended retention rules. It's the Cycles or Extended rules that are part of the issue on underutilized tapes.
I do about 400 backups per night, and I'd say that over 350 of them are in the same schedule policy. Having them all start at the same time, and all do their full backups on the same day help.
Any servers that do multiple full backups per week should have their own schedule, or their own schedule policy. If you use extended retention rules (I use 1st of the month, Monthly Fulls get extended by 180 days), having backups that do fulls on different days than your main schedule policies, but share the same storage policy, can really screw up tape utilization%.
Do fewer full backups. This is something I haven't implemented, but I sorely want to. With my extended rule being 1st of the month Monthly Full, I'm tempted to change my policies to do 1st and 3rd Friday of the month. What this does is if any backups from the 3rd Friday of the month fail, it gives me the rest of the month to re-run them before they get extended. This should help keep extended backups all on the same tape.

What happens to a tape that was 100% full, as retention period are
reached, and it is suddenly only 50% capacity? Is there a process to
copy that data to a new tape and return the original tape to scratch?
Perhaps you could make a copy of the still valid data, but it'd bo much more expedient to just let the entire tape expire when all the data has aged. There's other ways to keep like data on a tape, like starting fulls on new media, or using incremental storage policies so incrementals and fulls are never on the same media. Another method is to only apply extended retention to a secondary copy of the data.

media management
Hi guys,
I also have a question pertaining to Media Management, don't mind if I share it here while we're on the topic?
A customer of mine (performing daily full backups for about 15 servers) wants their daily aux copy jobs to different tapes every day.
Apart from that, they have actually customized their media barcodes to go by day, i.e. XXXXD1L4, XXXXD2L4, XXXXD3L4
(D1 for Monday, D2 for Tuesday, D3 for Wednesday, D4 for Thursday and so on)
The challenge here however, is that in a scratch pool, when all these tapes are loaded it they're "fair game" - i.e. any of the tapes can be used by the Aux Copy process. Making things even more difficult is that the customer prefers to load in 2 weeks worth of tapes at one go into the library, rather than exchanging tapes (i.e. export 01, import 02) on a daily basis. Any ideas how we can ensure that daily aux copies use the "correct" tapes without messing up the sequence?
I'm of the opinion that this is not the best way as it makes media management a hassle but the customer is adamant that this is how they prefer things to work, and they're unwilling to even look at the Daily Aux Copy Job Summary reports (which I've configured to e-mail to them on a daily basis) to find out what tape was used yesterday. They prefer to look at the label and go "ahh..D01, this is monday's tape!" rather than look at reports to show the actual information.
Hope you guys can provide me with some ideas here. Thanks!

From the properties of the Aux Copy Schedule, select Aux copy options and you have the choice to select “start new Media” and “Mark Media full after successful operations”. I am not sure if from the scratch pool, you can select a particular media for a particular job, but I may be wrong.

media management
Thanks for the feedback guys, I have already had the "Start New Media" and "Mark Media Full" options enabled.
And basing on the fact that tapes will only be scratched after retention parameters have been met, I was hoping for this model to work
(i.e. retention period of 13 days 1 cycle with daily full backups - tapes will retire after 14 days - hence technically, tape 02 (Tuesday) should only be scratched BEFORE Tuesday's Aux Copy a fortnight later. However, what I have noticed is that sometimes these retention periods don't play out as I would've hoped, and would sometimes be caught in a situation where Monday's Aux Copy which should've rightfully used 01 tapes, uses the 02 tape instead causing the media usage to be "off sync")
As for the scratch pool, I don't believe you can select a particular media for a particular job. I am having a tough time convincing my customer that this method is not the best way, and that the only way to TRULY ensure the tapes are use according to their liking is to insert the tapes daily, instead of loading in the entire week's tapes at one go, even though at the time of loading in, 6 out of the 7 tapes are marked full.

What happens to a tape that was 100% full, as retention period are
reached, and it is suddenly only 50% capacity? Is there a process to
copy that data to a new tape and return the original tape to scratch?
Perhaps you could make a copy of the still valid data, but it'd bo much more expedient to just let the entire tape expire when all the data has aged. There's other ways to keep like data on a tape, like starting fulls on new media, or using incremental storage policies so incrementals and fulls are never on the same media. Another method is to only apply extended retention to a secondary copy of the data.

media management
there is no automated process to do what the customer wants. you are on the right track with use new media and managing the tapes daily. 13 days and 1 cycle only equals 14 days if the customer is running fulls everyday which is generally is not the case. if the customer is running fulls once a week 13 days and 1 cycle is really 20/21 days as the 13 days is added to the last incremental in the cycle. otherwise the if the full was gone 13 days after it ran on day 14 you've basically invalidated the incrementals as the full no longer exists and its needed for the restore data/index. he'd probably be better off going by cycle length not days for tape management

media management
Hi,
Thanks for your response. Yes the customer is doing a full everyday as their data is relatively small and can actually afford running a full everyday.
I have also dropped a mail to Mike Dahlmeier regarding this and he (along with you and me) are pretty much on the same page with this.
Shall keep you guys updated after I have another round of discussion with the customer.
Thanks.

media management
They can load the tapes for 2 weeks and move them to a 'holding' tape pool which is not used for policies. Then every day they have to move the correct tape into the right scratch pool. There is still a daily task but at least they can load all the tapes at once.

Thanks for the feedback guys, I have already had the "Start New Media" and "Mark Media Full" options enabled.
And basing on the fact that tapes will only be scratched after retention parameters have been met, I was hoping for this model to work
(i.e. retention period of 13 days 1 cycle with daily full backups - tapes will retire after 14 days - hence technically, tape 02 (Tuesday) should only be scratched BEFORE Tuesday's Aux Copy a fortnight later. However, what I have noticed is that sometimes these retention periods don't play out as I would've hoped, and would sometimes be caught in a situation where Monday's Aux Copy which should've rightfully used 01 tapes, uses the 02 tape instead causing the media usage to be "off sync")
As for the scratch pool, I don't believe you can select a particular media for a particular job. I am having a tough time convincing my customer that this method is not the best way, and that the only way to TRULY ensure the tapes are use according to their liking is to insert the tapes daily, instead of loading in the entire week's tapes at one go, even though at the time of loading in, 6 out of the 7 tapes are marked full.

From the properties of the Aux Copy Schedule, select Aux copy options and you have the choice to select “start new Media” and “Mark Media full after successful operations”. I am not sure if from the scratch pool, you can select a particular media for a particular job, but I may be wrong.

Subject: Re: [commvault] media management
Hi guys,
I also have a question pertaining to Media Management, don't mind if I share it here while we're on the topic?
A customer of mine (performing daily full backups for about 15 servers) wants their daily aux copy jobs to different tapes every day.
Apart from that, they have actually customized their media barcodes to go by day, i.e. XXXXD1L4, XXXXD2L4, XXXXD3L4
(D1 for Monday, D2 for Tuesday, D3 for Wednesday, D4 for Thursday and so on)
The challenge here however, is that in a scratch pool, when all these tapes are loaded it they're "fair game" - i.e. any of the tapes can be used by the Aux Copy process. Making things even more difficult is that the customer prefers to load in 2 weeks worth of tapes at one go into the library, rather than exchanging tapes (i.e. export 01, import 02) on a daily basis. Any ideas how we can ensure that daily aux copies use the "correct" tapes without messing up the sequence?
I'm of the opinion that this is not the best way as it makes media management a hassle but the customer is adamant that this is how they prefer things to work, and they're unwilling to even look at the Daily Aux Copy Job Summary reports (which I've configured to e-mail to them on a daily basis) to find out what tape was used yesterday. They prefer to look at the label and go "ahh..D01, this is monday's tape!" rather than look at reports to show the actual information.
Hope you guys can provide me with some ideas here. Thanks!

Here is a list of what I have done to help get more tape utilization (though half-full tapes are still an issue).
As Jerome said, I use Incremental Storage Policies. My incrementals are 30 days, 1 cycle, and no extended retention rules. It's the Cycles or Extended rules that are part of the issue on underutilized tapes.
I do about 400 backups per night, and I'd say that over 350 of them are in the same schedule policy. Having them all start at the same time, and all do their full backups on the same day help.
Any servers that do multiple full backups per week should have their own schedule, or their own schedule policy. If you use extended retention rules (I use 1st of the month, Monthly Fulls get extended by 180 days), having backups that do fulls on different days than your main schedule policies, but share the same storage policy, can really screw up tape utilization%.
Do fewer full backups. This is something I haven't implemented, but I sorely want to. With my extended rule being 1st of the month Monthly Full, I'm tempted to change my policies to do 1st and 3rd Friday of the month. What this does is if any backups from the 3rd Friday of the month fail, it gives me the rest of the month to re-run them before they get extended. This should help keep extended backups all on the same tape.
"Landwehr, Jerome" <jlandweh < at > harris.com ([email]jlandweh < at > harris.com[/email])> 10/14/2009 9:26 AM >>>
What happens to a tape that was 100% full, as retention period are
reached, and it is suddenly only 50% capacity? Is there a process to
copy that data to a new tape and return the original tape to scratch?
Perhaps you could make a copy of the still valid data, but it'd bo much more expedient to just let the entire tape expire when all the data has aged. There's other ways to keep like data on a tape, like starting fulls on new media, or using incremental storage policies so incrementals and fulls are never on the same media. Another method is to only apply extended retention to a secondary copy of the data.
