Some files and folders disappeared from backup sets.
Recently, i've tried to restore some files from backed up Windows server with Windows Deployment Services. It is WDS images (.wim) files accidentially deleted on last week.
Symantec Backup Exec hasn't restored any files for me. C:\RemoteInstall\Images folder zero sized without any files/subfolders in it.
There are many backup sets of this server from 30th October 2013 but only one set from 18th December 2013 is normal. Any other is broken.
I do full backup every week and incremental backup every day.
Also i've seen strange thing: all full backup sets of normal size as 18th December backup set, but i can't restore needed files!
Restoration dialog for all backup sets except 18th December shows me zero sized folder without any files/folders in it.
Noone changes backup jobs setting, no errors in job journals, backup jobs ended succesfully. I've also done catalog operation with all tapes, but situation haven't chanded.
I have serious doubts that other backed up servers has the same problem. I haven't checked that yet.
