ReportIoError 2 - Further Info

Context
The first of the failed log backups was run after a series
of indexes on the database were rebuilt.
Recovery mode is changed to "bulk-logged" before rebuiding
indexes. This is followed by the log backup and then
recovery mode is changed back to "full".

Hi Kim,
When ever you perform a recovery model change, it is always suggested to do
a full database backup and
then goahead with Transaction log backup.
This I/O issue can araises due to free space in hard disk, permissions on
the disk.
Thanks

|||Thanks for the suggestion.
I'll add a full backup to the scheduled job before and
after the recovery mode change and see if the issue
persists.
