[Veritas-bu] [NBU3.4] Homemade HSM ready for Alpha-testing...
2002-06-05 10:27:18
Hi,
I just finished writing a homemade HSM system based on
Veritas and looking for some alpha-testers.
It is written in Perl (5.6.1) and Bourne Again Shell and
needs some additional modules from CPAN. It will:
- Cache backups on a diskcache
- Duplicate these backups to an other storage unit if
a) At least <To-configure> Bytes are to be duplicated
b) At least <To-configure> Jobs are to be duplicated
- Expires primary copies on the diskcache if a
watermark is reached (down to a second watermark)
*sorted* by a usage count and age.
E.g. if you do some restores on a cached backup it
will be expired this backup last and other backups
will be expired earlier (the primary copies).
- Log everything through syslog (local7.*)
On our site it has improved backup by a lot. Our DLT8000
drives running on around 4000 KBytes/s when using NBU
directly and MPX = 3. With staging we reached 7500 KBytes/s.
The staging unit may be simulate much more drives and slow
clients will not block your backup-drives.
If you would like to test the scripts you need a Unix-box,
Perl 5.6.1, bash2, some CPAN-modules and a diskcache with
more than 250 GBytes free (please do not use ufs or Soft-
ware-RAID5 on Solaris, its ugly slow).
Please expect errors and programming mistakes - it's alpha :)
Just drop me a mail if you are interested...
Bye, Oliver
