After MGMT upgrade to R80.40 - backups are smaller

Jump to solution

Hi

just recognized that after upgrade from R80.30 to R80.40 &JHF of a SMS / MDS the size of the backup / mds_backup are dramatically smaller.  30-40% less which is great. Less than 20 GB now.

Tried to understand the reason behind and saw that they  are much less on the updated box:

- mgmt_backup_dump_gaia.gz is much smaller (what is that?)

- a lot of logs have been deleted or not converted (journal.csv, RFL.log, solr.log)

 

Do you recognize the same?

Or did we simply have had suboptimal configuration which creates tons of logs.

Regards

Hi, 

This is correct.

When upgrading a MGMT sever / MDS from R80.20 or higher version, the upgrade is being done by a new process (under the hood). In the new upgrade process only the latest revision is being upgraded. More information and behavioral changes can be found in sk163814.

This may explain the smaller backup size after upgrade form R80.30 to 80.40.

 

Thanks, 

Itai

I noticed something very similar on regular firewalls before as well, specially comparing size of scheduled backups after upgrade. Oddly enough, I noticed same difference in backup size in cluster config, though that could be expected, as only master would process traffic, so thats probably normal.

 

I really cannot say why upgrade would cause that issue, as I had never seen it back in R77 and before that days, but in R80, maybe since database is way different, not really sure.

Might be worth asking TAC about it...would be nice to get official answer.

Hello

They are smaller because there are not containing database revisions that were created during r80.30 lifetime.

Well, you do make a point there, but not everyone was making database revisions back before R80 though : )

Sorry, just re-read your response...wait, I thought its exactly the same how those changes are saves automatically in any R80 version. I dont believe its different in R80.40 compared to R80.30, but I could be wrong.

After the upgrade to r80.40 the database sessions concerning r80.30 are not included at r80.40 backup files because they don't have any value for restore as far as i understand it.

Hi,

at least I can confirm that all old (R80.30) revisions were gone after upgrade. And this was definitely quite a lot.

Thanks, Regards
