[gpfsug-discuss] mmbackup file selections

[Paul Ward]

Thank you.

We run a script on all our nodes that checks to see if they are the cluster manager.
If they are, then they take responsibility to start the backup script.
The script then randomly selects one of the available backup nodes and uses dsmsh mmbackup on it.

Where does this command belong?
I have seen it listed as a export command, again where should that be run - on all backup nodes, or all nodes?


Kindest regards,
Paul

Hi Paul,

If you run mmbackup with "DEBUGmmbackup=2", it keeps all working files even after successful backup. They are available at MMBACKUP_RECORD_ROOT (default is FSroot or FilesetRoot directory).
In .mmbackupCfg directory, there are 3 directories:
updatedFiles  : contains a file that lists all candidates for backup
statechFiles  : cantains a file that lists all candidates for meta info update
expiredFiles  : cantains a file that lists all candidates for expiration

Hi, I am trying to work out what files have been sent to backup using mmbackup. I have increased the -L value from 3 up to 6 but only seem to see the files that are in scope, not the ones that are selected. I can see the three file lists generated ZjQcmQRYFpfptBannerStart

Hi,

I am trying to work out what files have been sent to backup using mmbackup.
I have increased the -L value from 3 up to 6 but only seem to see the files that are in scope, not the ones that are selected.

I can see the three file lists generated during a backup, but can't seem to find a list of what files were backed up.

It should be the diff of the shadow and shadow-old, but the wc -l of the diff doesn't match the number of files in the backup summary.
Wrong assumption?

Where should I be looking - surely it shouldn't be this hard to see what files are selected?


Kindest regards,
Paul
