SQL Server事务日志备份失败665“由于文件系统限制，请求的操作无法完成”

Question

I am taking the transaction log backup in SQL Server 2012 for the database "XXXX".

While taking the transaction log backup (after executing 60%), it throws this error:

Backup failed for server AAAA (Microsoft.Sqlserver.SmoExtended)
Additional Information:
System.Data.SqlClient.SqlError:
Write on "" failed 665: (The requested operation could not be completed dut to file system limitation)

Please assist.

I recommend you:

1. Run a Windows defragment on the volume where the spooling folder is located.
2. Alternatively, pick a different, less fragmented volume to spool the database to.

When a sparse file (used for snapshot database files) is populated Windows limits the amount of data that may reside in the file. Once the amount of data stored in the sparse file exceeds the limit further data storage in the file may be prevented.

Also:

• Run DBCC CHECKDB in OFFLINE mode ( WITH TABLOCK )
• Run DBCC CHECKDB at a time when less data modification is taking place
• Divide the database into a few more files. The limitations are per sparse file and each database snapshot creates matching sparse files for each database file. For example if the database files are each limited to 64GB in total size you can't exceed the limitation on a per file basis.
• Remove snapshot databases that have grown large.
