I noticed that a snapshot backup to a local disk takes 5 min, while the same backup on NAS in suspend mode takes longer than 4 hours.
The two tests was done on two server (same CPU and RAM, same contents and same VM's in different datacenter), I cannot compare the two backups timing because the first server hasn't NAS device and the second one hasn't enough free space for snapshot (OVH configuration).
Now I'm approaching to resize the HD on the second server, so I wonder which solution would be the best for daily backups (I have 1TB HD in raid1 and NFS 100GB NAS):
A) reduce the HD size to free up 10 GB so I can do the snapshot backup on NAS device (How much time I'll need?)
B) reduce the HD size to free up 10 GB for snapshot and 100 Gb for a backups dedicated partion.
- Mounting the backup folder to this new partion
- Planning the backup with snapshot on this local folder
- Using rsynk to syncronize NAS and backup folder in background.
Any tips?
