Re: Manual health check?

Ok, so with "scheduled health check" you mean to run the Validator against all jobs; and the Health Check option of the Backup Copy jobs does the same of the Validator. Am I getting this right?

During the health check, Veeam Backup & Replication calculates checksums for data blocks in the backup files stored on the target backup repository and compares them to the checksums that were previously stored to the backup files. Health-check always verifies only the most recent restore points for the VM(s) processed by the backup copy job.

Validator basically recalculates checksums for all data in the backup chain and compares the results to the previous value.

The difference is that health check tests if there is a difference between source and target, while validator checks if there is a difference between how current data looks like and how it should look.

Pavel, sorry to keep bugging you, but you imply that health check and Validation are two different things.
However, you say:
PTide wrote:Yes, that's possible with powershell script.
The script you reference does nothing else than run the Validator against all jobs. I still don't see how I can schedule a health check (=different from Validation) then.

There is no such thing for backup as health check since health check operation compares source backup (original backup) and target backup (copy job backup). In your case you need to use validator (automated with script) in order to confirm that your original backup files are good. Health check can be scheduled for backup copies only and will confirm that they are actually copies of your original backup.

[MERGED] Request: Schedule Compact/Healthcheck independently

Post by andreash » Jan 27, 2016 3:04 pm 1 person likes this post

Hi,

I'm trying to find an ideal solution for scheduling backup and backup copy jobs in VEEAM9.

My scenario:
~50 VMs with ~10TB Data in total, Backup and Backup Copy jobs
I have set up 6 forever forward Backup jobs with equal backup size, each job is ~1TB on disk on one single RAID10.
The jobs are staggered by 1-2 hours, depending on the average run time of each Backup job and its Copy Job.
Each Backup Job is complemented by a Backup Copy job which is started right after the Backup. These jobs flow to three RAID5 Arrays.
I'm quite happy with this setup so far.

But I also need to schedule frequent healthchecks and compact jobs. Unfortunately these are tied into the Backup and Backup Copy jobs, run either before or after the backup taks, and influence the I/O load on the storage during the backup window.
I'd perfer to be able to run these outside my backup window, i.e. during the day or over the weekend, when there is plenty of I/O to spare.

Would this be possible in an upcoming Veeam 10? :-)

Regards,
Andreas

[MERGED] Compact of Full Backup

Post by owenw » Nov 08, 2016 3:25 pm

Hi guys,

Can I raise a feature request:

I want to be able to schedule "Compact of full backups" separately from my backup jobs.

Currently "Compact of Full Backup" seriously impacts our backup scheduling as we have a scheduling window which we can complete disk backups in comfortably, however when we copy this data to tape we are against a tight window. When "Compact of Full Backup" runs (for several hours) this extends this initial step significantly, our tape jobs fail to complete within schedule etc.

An issue I have identified recently is where the "Compact of Full Backup" occurs outside of our scheduled window (Scheduled for Sunday but happens Monday night this week) which I assume is some form of automated attempt at housekeeping.

Thanks
Owen

Hi,

Thanks for the links. I have already digested this prior to posting.

The first link provided leaves me assuming that the compact operation is entirely dependent on the backup job being triggered the same day that the compact is scheduled, since there is no information in the docs (links provided) indicating either way if this is the case. As in my personal experience, I DONT want this occuring in the middle of a backup process (process for me being backup to disk, then dupe to tape).

Regards
Owen

Currently, that is not possible. However, how often do you run compact full operation? What schedule does you tape job have? Thanks.

I run backups Monday to Saturday to disk.
I also run to tape Monday to Friday (no operators around to swap tapes Saturday)

I have limited windows for compactingbackups, hence this feature request.

When I had compacting enabled in my jobs, scheduled for Sunday, although backups were only scheduled for Mon-Sat, the compacting would kick in on Monday nights which was not helpful or expected. The docs are less than clear about behaviours etc of compacting around dependencies of backup job schedule must match compacting schedule.

Im not the only person affected by this and believe this is a real issue for the wider community as this doesnt just affect the disk jobs, but in its current implementation has roll on impacts to tape jobs which isnt ideal to say the least.

Right now I have rescheduled this to run on Saturdays after my saturday disk job, as I dont have a saturday tape job to be affected. This is a change I have only made this week so Im waiting for the weekend to validate this works as expected. If thats the case, Ill likely update this to run the last saturday of each month.

Im aware that scheduling this outside of the disk job isnt currently possible, but can you confirm this has been logged as a request please?

Many thanks
Owen

Yes, every feature request posted on the forum is accepted.

Btw, your understanding of compact scheduling is correct, it is performed after applying retention at the end of the successful job cycle.

[MERGED] Feature Request - Separate Maintenance Schedule

Post by JoshuaPostSAMC » Nov 21, 2016 9:05 pm 2 people like this post

I would like to see an option to have a separate schedule for when maintenance tasks run, such as Merge, Compact, and Health Check.

I have 17 jobs that run overlapping each other. As I started moving towards Forever Forever Incremental, when a job started the merge process, the backup speed for other jobs slowed down. Then another job would finish and start merging and all remaining backups would slow again, rinse, repeat. Even worse when one starts a Compact operation. I have my Compacts separated out so only one job will do a compact per day.

Ideally, I would like to hold off on all of these types of tasks until a set time, such as 3:00 am when all of my backups are done, and then let the merges go to town, when they won't impact the backup window. Would want an option to do the sequentially, or to let them overlap.

Anyone else see this as helpful?

I have enabled`Storage-level corruption guard` on copy jobs once a month. But since v9 I can also enable on primary jobs too, the trouble is my primary jobs are daisy chained to run after each other, so if I schedule a health check on job1 all the others get pushed back, which then also pushes the offsite copy jobs back too. It would be good if corruptions checks had their own schedule or a manual trigger (like when a HDD dies and rebuilds or a raid parity error gets auto corrected)

+1 to the feature request for separate health checks & compact operations. Would also like to be able to run these on the weekend, during the day, separate from our normal nightly processing window. Thanks!
