[Veritas-bu] Configuring NAS !
2003-03-04 22:55:44
It all depends on what works for you. Here's a quick list of pros and cons
(long list in my book, Using SANs and NAS)
1. NDMP
- Lower performance overhead than NFS/CIFS
- Will be sure to get all ACLs
- Sometimes better performance than NFS/CIFS
- Backup prioritized behind regular NFS/CIFS requests
- Backups are in a proprietary format only usable on that
manfacturer's filer.
(yes, you can often read the tapes with dump/tar,
but what a pain, and you'd lose the ACLs)
- Often can't share NDMP tape drives w/other (non-NDMP) backup
clients
- Many NDMP implementations leave a lot to be desired
2. NFS/CIFS
- Mixed filesystem drives (NFS/CIFS) must be done via CIFS,
or you lose the ACLs
- Cannot distinguish regular NFS/CIFS requests from backup traffic
- More network load on Filer
- More flexible, since can share tape drives with other clients
- More portable, since backup in your backup s/w's format
