I am not sure what you're saying about migrating and removing the tape. |
13 |
If you mean you're going to install Fedora (2.4 kernel), then I would |
14 |
assume your tape drive will work fine. It appears that your scsi card is |
15 |
not fully supported in the 2.5/2.6 kernel. |
16 |
|
17 |
If you're looking for alternate solutions to use with gentoo/2.6 kernel, |
18 |
then I would suggest investing in a new scsi card. The tape drive and |
19 |
cable should be fine (assuming proper maintenance of the tape drive). |

I personally have moved away from tape for smaller data sets ( < 100GB |
22 |
), as tape has some issues. First, you need to keep the tape head clean |
23 |
and second tape media has a limited useful life span. I have been |
24 |
burned a couple times by defective tape media in a restore situation. |
25 |
|
26 |
If an external hard drive is out, how about removeable hard drives? |
27 |
Remeber, the point of a backup is just to keep the data in multiple |
28 |
places. You can easily add a removeable drive cage to a system and |
29 |
purchase a couple extra caddy's. This way you can alternate between 2 |
30 |
or 3 removable hard drives for backup devices. Some removeable trays |
31 |
support key locks, in case you're worried about physical security. |

The method I use is the dar program in conjunction with cdrecord-prodvd. |
34 |
I create a full backup monthly, then create a weekly incremental against |
35 |
the full backup, and then daily backups against the weekly. This method |
36 |
only requires me to burn multiple dvd's once a month (as my monthly |
37 |
backup is in excess of 20GB). After that, I get away with one extra dvd |
38 |
per month (ymmv). For a recovery scenario, I may have to go through |
39 |
multiple restores to bring the system current, but thats a trade off I |
40 |
make to save on media. |
41 |

Those are just a few ideas. There are many other ways to backup data. I |
43 |
believe there is even an online service you can sign up for, and back up |
44 |
to their servers. IIRC you pay by the backup size in 10GB increments. |
45 |
|
46 |
Backup solutions are unique to each enviroment and use. |
47 |
Things to consider are; hard costs of backup hardware and media, time |
48 |
required to perform backup and does data have to be taken offline, ease |
49 |
and automation of backup, time required to restore data, ease and |
50 |
automation of restore, and physical storage of backup media (it doesn't |
51 |
do you any good to keep all your backups in the same building as the data |
52 |
if the building burns down). I am sure there are other factors too, this |
53 |
is just to give you an idea of things to think about when trying to |
54 |
come up with a new backup solution. |
