You can find an appendix about ASE there.

Hi Andreas,

thank you for reply but I've some questions:
you mean in backup job: guest processing - enable application-aware processing - applications - select VM - edit - Tab "SQL" and here "backup logs periodically". Is that correct?
On VM the "Windows Shadow Copy" Service is running (C:\Windows\system32\vssvc.exe)

Is that correct?
Thank you very much.
BR, Christoph

Hi,

No, for SAP ASE backup you need to make sure that you have "Enable appliaction-aware processing" option enabled as well as "Require successful processing" in "General" tab. Please check the whitepaper Andreas has provided you with the link to, p.67

Thanks

There is another Appendix for MS SQL maybe it was the wrong appendix.

These settings I've configured from the beginning last October but in my opinion that's not a consistent backup for sybase ASE databases because I'm not able to recover database from e.g. 1 hour ago, only whole VM from last backup (every day @22:00)? And my SAP partner told me that transaction logs etc. are growing bigger and bigger and I should delete them. I don't have these problems with MS SQL Server?!

There are three options mentioned in the appendix, which one have you configured?

All 3 options were documented with the intention to bring ASE in a consistent state to backup on image level. (and use VM/Instant VM and File Level Recovery).

You need to handle logs with native scripts from ASE.
Veeam do not provide any tool to delete logs over time and restore to a specific point in time with ASE. (No Veeam Explorer for ASE available).

It is common that the ASE partner have some bavkup scripts that can be modified for Veeam there.
For example you can run your logfile handling script at post script in the Veeam job.

If I understand correct - I want consistent backup of Sybase ASE DBs with a max delta of for example 1h. So I had to schedule the backup job periodically every hour (or less) to get consistent backups? is that correct? So if original VM gets broken I could restore this VM from backup with e.g. 1h delta (means backup 1h ago) without any issues?

And with postscript I could delete log files etc.

Yes, thats one of the option. You can then restore to the point of backup with Veeam. If you have one database per server, you can use Instant VM Recovery to bringt the service back within ~5 min (2min + OS boot).

Another option would be to backup once a day ( or more frequent with Veeam) and backup the logs with a generic ASE command to another server. Then there is maybe an option to restore the database with Veeam (maybe file restore, Instant VM Recovery or Database dump restore) and then rollforward the logs with "until_time". I am not a ASE specialist so you need to work with one to get this done and tested.
If you can schedule the logbackup high frequent this would give you better RPO but less RTO compared with my first option above.

ok, this sounds good for me.

Just another (maybe stupid) question: what's the best way to backup and replicate these Sybase VMs? Backup every full hour, replication every half hour?

It depends on your needs.
You can consider Replication from Backup maybe to tansport data only once.

At Replica 28 Restore Points are max.
If you need a very high restore point amount at Backup job, consider Syntetic Full with Incrementals (~max 60 incrementals per synt full).

Any one can share their current setup on backing up the SAP ASE DBs?

Do i really need to setup VSS for the DB server?
