Our incr backup fails consistently in the last few days. It starts alright but after a few gigabyte on the client we get the error:
ANS1301E This operation cannot continue due to an error on the IBM Spectrum Protect server. See your IBM Spectrum Protect server administrator for assistance.

On the server side we see:

18-08-2023 22:57:25 ANR2012W Error encountered for storage pool directory:
\\medbackup.med.ad.bgu.ac.il\tsmc1 in storage pool:
CPOOL. (SESSION: 194578)

18-08-2023 22:57:26 ANR0951I Session 194578 for node MEDFS2 processed 9 files
by using inline data deduplication or compression, or
both. The number of original bytes was 307,709,100.
Inline data deduplication reduced the data by
236,446,618 bytes and inline compression reduced the
data by 0 bytes. (SESSION: 194578)
18-08-2023 22:57:26 ANR0403I Session 194578 ended for node MEDFS2 (WinNT).
(SESSION: 194578)


Then we find one or more containers unavailable. We fix the containers with "audit container ... action=scanall"
No errors are found. But the next backup will fail again.

The server is on 8.1.17, the client as well.
The containers are on a number of disks on a shared windows server 2019. There have been some updates on the windows server recently. (KB5029247,KB5029647)

The audits are fine, data is accessible, but backups fail.
Any ideas ?
