[Bacula-users] STK SL-3000 experiences
Hi guys, Has anyone got any experience using bacula with the Storagetek SL-3000? Or the SL-150 for that matter (they should behave the same way for what I'm told) I'm looking for real-life experience here, not something like if it can be managed with mtx, then it _should_ work..

[Bacula-users] Plans for support block-based dedupe?
Ok, it seems to me that there is some confusion of which kind of dedupe I'm referring to. What I'm talking about is variable-length block-based target dedupe, that is, the DXi or DataDomain box receives all data from the client via the backup server (bacula SD) and then handles the deduplication and compression of these data. There is no dedupe or compression on the client or backup server itself of any sort. This does not work in practice right now, since bacula does something to the backup stream that makes most of the blocks or segments unique. I've tried this on a DXi and on a fileserver using SDFS, and both had only 5% data reduction after running three 6GB backups of the same filesystem on a client. In theory that should give us at least 66% data reduction ratio. Please bear in mind that target dedupe is pretty much the industry standard, since RTO plays a huge role in deciding what type of backup and storage to use. /tony +-- |This was sent by tony.alb...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- -- Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.

[Bacula-users] Plans for support block-based dedupe?
Hi Silver, The downside of client-side dedupe is actually a combination of several things. 1. The client does the dedupe calculations etc. this means that it takes CPU resources on the client which it might not have. 2. Sometimes, client-side dedupe is chosen because of bandwidth limitations to the backup server (remote offices etc). In case of a large restore all files will have to be sent from the backup server to the client anyway, and this can be almost impossible because of the time it will take. That's the RTO side of it. 3. Partial restores can only be made to the client that did the backup, not to another client if necessary(redirected recover). There are probably more, but these are just what I can think of straight away. /tony +-- |This was sent by tony.alb...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- -- Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.

[Bacula-users] Plans for support block-based dedupe?
Spooling is definetely off. using tar to dump the directory 3 times now. 1. Before first tar: [root@dkarhbus02 download]# sdfscli -volume-info Volume Capacity : 1.5 TB Volume Current Size : 681 B Volume Max Percentage Full : Unlimited Volume Duplicate Data Written : 0 B Volume Unique Data Written: 96 KB Volume Data Read : 1.9 MB Volume Virtual Dedup Rate (Dup/Total Bytes Written) : 0% Volume Real Dedup Rate (DSE Size/Total Bytes Written) : -1.46195E7% Volume Actual Storage Savings (Unique Blocks Stored/Current Size) : -2.11037458194E9% [root@dkarhbus02 download]# 2. After first tar: [root@dkarhbus02 download]# sdfscli -volume-info Volume Capacity : 1.5 TB Volume Current Size : 6 GB Volume Max Percentage Full : Unlimited Volume Duplicate Data Written : 32 KB Volume Unique Data Written: 6 GB Volume Data Read : 1.9 MB Volume Virtual Dedup Rate (Dup/Total Bytes Written) : 0.0% Volume Real Dedup Rate (DSE Size/Total Bytes Written) : -221.98% Volume Actual Storage Savings (Unique Blocks Stored/Current Size) : -221.98% [root@dkarhbus02 download]# 3. After second tar: [root@dkarhbus02 download]# sdfscli -volume-info Volume Capacity : 1.5 TB Volume Current Size : 12.1 GB Volume Max Percentage Full : Unlimited Volume Duplicate Data Written : 12.1 GB Volume Unique Data Written: 96 KB Volume Data Read : 1.9 MB Volume Virtual Dedup Rate (Dup/Total Bytes Written) : 100.0% Volume Real Dedup Rate (DSE Size/Total Bytes Written) : -60.99% Volume Actual Storage Savings (Unique Blocks Stored/Current Size) : -60.99% [root@dkarhbus02 download]# 4. After the third tar: [root@dkarhbus02 download]# sdfscli -volume-info Volume Capacity : 1.5 TB Volume Current Size : 18.1 GB Volume Max Percentage Full : Unlimited Volume Duplicate Data Written : 18.1 GB Volume Unique Data Written: 128 KB Volume Data Read : 1.9 MB Volume Virtual Dedup Rate (Dup/Total Bytes Written) : 100.0% Volume Real Dedup Rate (DSE Size/Total Bytes Written) : -7.33% Volume Actual Storage Savings (Unique Blocks Stored/Current Size) : -7.33% [root@dkarhbus02 download]# Which looks good to me. Now, we delete the tar files and do 3 backups using bacula: 1. After first backup: [root@dkarhbus02 ~]# sdfscli -volume-info Volume Capacity : 1.5 TB Volume Current Size : 6 GB Volume Max Percentage Full : Unlimited Volume Duplicate Data Written : 0 B Volume Unique Data Written: 6 GB Volume Data Read : 1.9 MB Volume Virtual Dedup Rate (Dup/Total Bytes Written) : 0% Volume Real Dedup Rate (DSE Size/Total Bytes Written) : -321.8% Volume Actual Storage Savings (Unique Blocks Stored/Current Size) : -321.81% You have new mail in /var/spool/mail/root [root@dkarhbus02 ~]# 2.

I haven't got the DXi online right now, but I'll test it out when I do and get back on that. /tony +-- |This was sent by tony.alb...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- -- Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.

[Bacula-users] Plans for support block-based dedupe?
Hi everyone, Does anyone know whether bacula can be made to work on a block-level dedupe storage system? Are there any plans to support this technology? The reason I ask is that I've gotten a few requests from people who have devices like Quantum DXi's or DataDomain, and these both do block-level deduplication. Of course I could try to persuade them into using some other backup software(I'm actually working as a EMC NetWorker consultant), but they are on a limited budget. /tony +-- |This was sent by tony.alb...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
