Hi all, My only encounter with tape-backup was with Windows 2000. With it, when we backup things using windows' backup tool, it will create a 'catalog', then the catalog contains all the backup operations we do based on date. So, with this we can "append" many backups into one tape. Next time we want to restore a backup, we can choose what date available in that particular tape. I have zero experience with tape on Linux. I've been googling around and it seems that the backup operation is very different. For example: - The tape is 400GB (LTO-3) - The data is only 10GB Some of the articles I read imply that 1 tape contains 1 backup-file only. CMIIW. This is certainly not very efficient. The commands used are: mt, either tar, cpio. My question is: 1. How do I use that one tape of 400GB to store 39 archives of backup into it in Linux? 2. Is tape backup seen by Linux just like any other filesystem? Can we mount it and 'ls -l' it? 3. When to rewind, forward, why? 4. Wel will only backup data/files (not the entire filesystem), is it enough to use the software provided by the tape vendor, or do I need another software? Or just the mt command will do it? Any URL, scripts, insight are very welcome.

Legato (from EMC) Symantec Backup Exec and its big brother NetBackup Tivoli StorageManager (from IBM) HP DataProtector Express (hoary, but quite robust and cheaper than the above) and there's a bunch of smaller players, like NovaStor, Yosemite, etc the big ugly with all of these is the tape formats and catalogs are generally NOT interchangable. btw, I would think twice about keeping 40 daily backups on the same tape, thats a lot of eggs in one basket. LTO /is/ quite reliable, but still...
I found Amanda rather complex for what we wanted to do (simple backup of a single server to a single tape drive). We eventually decided on BRU (www.tolisgroup.com). It's not free, but the simple 'workstation' version isn't very expensive. Their support staff are really helpful as well. Free download for trial if you wish. -------------- next part -------------- An HTML attachment was scrubbed...

Not too costly (I'm on a legacy version, 5.3 - the Network Backup (ANB)) and I've been extremely happy. In fact, it was put to a real world test recently when one of my servers died hard....and it passed with flying colors. Easy setup (rpm) and fast reindex and restores got up and running quickly. Just my .02. YMMV, -Ray
