We have given our users privilege to take snapshots. But now it is uncontrollable and people started taking meaningless snapshots and never deleting it.
Due to this we are facing performance issue, Disk space overloaded issue and etc.
I would like to prevent users from taking snapshots beyond certain limit.
For example.
Our sys admin has created a backup system which create snapshots of the hard drive.
When I try to restore older version from the snapshot:
cp /path/to/snapshots/foo.bar /path/to/folder/foo.bar
I get an error:
cp: `/path/to/snapshots/foo.bar' and `/path/to/folder/foo.bar' are the same file.
I have a VM that seems to be working ok, but when VMWare DR (or I) tries to create a snap shot, it fails, and when I view the summary page of the VM it has a warning at the top showing that the disks need to be consolidated.
So I go to snapshot manager for the VM and choose consolidate (in snapshot manager, there are no snapshots actually listed by the way).
I'm planning on using LVM in order to be able to take atomic snapshots of large files and rsync them to a remote site.
What I'd like to know is whether there is any long-term impact on the main (non-snapshot) volume: if I typically keep the snapshots for 24h before dropping and creating a new snapshot, does the main volume get progressively more fragmented?
This question is similar to Ubuntu keeps creating dummy directories, except it's about the ~/Snapshots directory. I don't have that startup application, and I've moved all of Ubuntu's directories away from there - the only one I can't find is the Snapshots.
I need to run some VMs But it seems like VMWare Player doesn't support snapshots.
Is there any other free software from VMWare that support snapshoting?
PS: I know that Oracle VirtualBox can do that but I am interested in VMWare products at the moment.
I am working on a Java program that accesses a set of several thousand files on disk, reading all or part of each one. Disk access performance determines my program's performance. Running this program on an Ubuntu 10.04 VM (under VMWare Fusion), I noticed performance speeding up. This was consistent with vmstat results, which showed a peak input rate of 125 MB/sec.
ec2-describe-snapshots -O xxxxxxxxxxxxxxx -W yyyyyyyyyyyyyy
Just gives me the 'usage', as if I'd written ec2-describe-snapshots -h with no other arguments.
The Next3 filesystem offers lightweight snapshots and is compatible with...
