SAP HANA Backup error

[Former Member]

Hi all,

When trying to run a Backup in HANA Studio we get an message/error which reports that the backup is failing.

The shared folder where the backups will be stored has the necessary permissions set.

The error we get is:

Could not start backup of system 'SH1'. ' Cannot open file ""<root>/.log_backup_0_0_0_0.1385931567067" (mode= W, access= rwrwr-, flags= DIRECT|UNALIGNED_SIZE|TRUNCATE|MULTI_WRITERS), factory= (root= "/mnt/backup/log/" (access= rwrwr-, flags= AUTOCREATE_PATH|DISKFULL_ERROR, usage= LOG_BACKUP, fs= UNKNOWN (cifs), config= (AsyncWriteSubmitActive=auto,AsyncWriteSubmitBlocks=new,AsynReadSubmit=off,#SubmitQueues=1,#CompletionQueues=1)))", rc=22: Invalid argument'

Does anyone have an idea of what we can check to resolve this error?

Thanks in advance!

The problem was with NTFS shares from windows.

We changed the backup location to an NFS share & the backups works now.

Verry annoying that the HANA backups don't seem to support NTFS (cifs in linux) shares.

Dries,

Just curious. Where you able to create, edit, modify and delete files from the NTFS partition as an HANA OS user by running simple commands like touch or vi? If that worked, I would assume the backup program should also have worked.

This is an interesting information which I like to know.

Thanks,

Jackson

Hi John,

Yes, I have tried the folowing operations (as <sysID>adm) on the File share.

- Created a file - edit & save that same file - Afterwards deleted the file.

All the operations above worked. The NTFS Share was set-up using Windows Server 2008.

Unfortunately the HANA back-up did not work on this share. (See the error in 1st post)

As mentioned, the solution for us was to use an NFS Share...

Perhaps in the future we will investigate this further as the current back-up situation is not ideal for us.

- Perhaps someone has already managed to get it working on NTFS shares? 🙂

Geert,

I have tried with NTFS Windows Share - no luck. With NFS Windows share works perfectly.
