Backup doesn't work

Hey,

I've made backups of serveral VMs, but it seems that the backups doesn't work. The original .vmdk file is round about 30 to 100 GB but in my --backup-point the .vmdk file is only 1 kb. Is that right?
I used following backup commands:

./xsibackup --backup-point=ip:port:/path/to/backup/location --backup-type=all --backup-prog=xsitools:z
./xsibackup --backup-point=ip:port:/path/to/backup/location --backup-type=all --backup-prog=rsync

On both commands the .vmdk file is only 1 kb.

Now when I copy the files of the backup from the deleted VM back to my vsanDatastore I can register the .vmx file. But when I start the VM it display an error that says it can't find the files.
Can someone help me?

LG

Re: Backup doesn't work

You used xsitools, that is a deduplication engine, so the .vmdk contains just the "indexes" to the data chunks, you ave to restore the vm prior to be runnable

Re: Backup doesn't work

I also tried "rsync" but got the same error.
So what you mean is that i had to configure a new VM with the same name and configurations?
Or how can I restore the VM when it is deleted?

Re: Backup doesn't work

Just like you need to know how to use some tool before actually using it, i.e. a wrench, you need to know what deduplication is before using it.
https://en.wikipedia.org/wiki/Data_deduplication

Apart from that, Free version does not allow to restore deduplicated backups, thus, if you just want to perform simple backups, do not use --backup-prog=Xsitools:z, but --backup-prog=Vmkfstools instead.
