[PLUG] cru vs. veritas backup utilities

[Fred K Ollinger <follinge@sas.upenn.edu>]

Anyone have opinions on cru (bru) vs. veritas utilities?

We have 1.5 TB that needs to be backed up to tape nightly. We have a tape
system that can handle this: 100 GB/tape.

We are using dump currently. This has successfully restored from bare
metal to a working system. However, there are some problems with dump:

1. allegedly, it's not recommended for the ext2 fs:

2. Although dump works great w/ multiple tapes, I never got a restore
script to work that way so I had manually change tapes to get a
restoration done. Ugly.

3. restore is really slow. A better utility would keep a current list of
files to restore that can be browsed off-line then it would automatically
change tapes to restore just the files that I need. This is similar to
problem #2.

4. If #3 were in place, then we could probably have compression enable to
squeeze out at least 40% more/tape.

Beyond these simple things, dump/restore works great.

Any utility that does dump/restore plus the above 4 is welcome, OSS or
proprietary.

Thanks for listening.
