My maintenance plan backup failed the other day with the following error and from my research I found that it was likely caused from not having enough disk space, which there was not sufficient space to do the backup. I removed a ton of space and it failed again last night with there being 55GB free space, when the DB is only 16GB. Executed as user: NT AUTHORITYSYSTEM. sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed. After I freed up some space, the backup ran okay, but the maintenance plan was still failing with the same error message. The only change I made to this Maintenance Plan backup recently, was I moved it from 6:00am to 7:00 am in the morning and I don't see anything else conflicting. My suspicion is that because this "step 1" of the plan also contains the deletion of files older than 1 day, that maybe this last setp failed after the backup was completed. I do see that it is not deleting these older files. Do you suppose that by changing the time of the backup, it would make this last step of the plan fail? This is the only reason I could think of. Below is the MP script: EXECUTE master.dbo.xp_sqlmaint N'-PlanID EB943500-B818-425F-B9B8-20EBE92FFC8D -WriteHistory -VrfyBackup -BkUpOnlyIfClean -CkDB -BkUpMedia DISK -BkUpDB "Erogram FilesMicrosoft SQL ServerMSSQLBACKUP" -DelBkUps 1DAYS -BkExt "BAK"' Thanks.
