Hi
I have ESXI 4.1 running on a HP Proliant managed by Vsphere
the VM is a single Windows Server 2008 R2 Std
it is running on a datastore which is a 250GB hard disk on the proliant
I have a 1TB disk also which I use as the data drive and this is added as a second disk.
this allows me to disconnect the 1TB disk. run and export of the shutdown VM and effectively backup just the VM
the data on the 1TB disk I backup from within Windows on a daily schedule.
I run this procedure of shutting down the VM
disconnecting Hard Disk 2 which is the 1TB data store
running the export
and then reconnecting the Hard Disk 2 and restarting the VM
this has worked great until last night.
when I restored the data store it has restored one that is date about 2nd February 2013.
I cannot figure out what has happened and really need some help to avoid running into this again
luckily I can recover all the data from the nightly backups as I ran a backup before doing the above procedure.
I am mystifed.
here is what I noticed when disconnecting the Hard DIsk 2 last night.
I had last done this procedure on the 2nd of Feb and backup up the VM
after shutting down the VM and exporting it then I went to add the Hard Disk back in I could only see one dated 2nd Feb
the thing is I assumed this meant the date it was last created so didnt think too much about it. The datastore is most all of the 1TB disk so it isnt like it can store two of them on the disk. there was just two files vmdk files and that is what I expected to see.
I booted it all up and checked the Windows server to be certain the data failes were available and it looked fine
I didnt check dates but once staff came in this morning it started be clear that nothing past 2nd feb existed and effectively I had added Hard Disk 2 back in from that date.
I have two questions I cannot answer
1. where the hell is the data store frrom last night before disconnection? I just disconnected it and did not click the option to delete the data.
2. how can a 1TB datastore from 2nd Feb suddnely show up in its place.
if anyone can help me solve this I would really appreciate it.
