Item<\/th>\nRecommendation<\/th>\n<\/tr>\n
OS volume<\/td>\nThe file backup agents are file data backup tools and are not designed to backup the operating system. Only capture data files. For operating system backup, contact CyberSecure for a solution designed to backup the entire OS.<\/td>\n<\/tr>\n
Don’t backup the root of volume or drive letter, eg selecting the top-level C:\\ or D:\\<\/td>\nThis will include hidden and system files that are stored in the root of a volume. Any files saved to this location in future will be added to the backup. Best to backup the specific folders you need<\/td>\n<\/tr>\n
Structured databases<\/td>\nSQL<\/a> or Exchange<\/a> databases are structured data and require their own backup set. Use a separate specific backup set type to capture these. Exclude them from the file backup set to avoid duplicating data.<\/td>\n<\/tr>\n
Number of files in backup set<\/td>\nFor performance and reliability keep the number of files in each backup set ideally below 500,000 (and definitely below 1 million).<\/p>\n

If the restore process is interrupted it cannot resume, so having a larger backup set means a slower restore time if the transfer needs to resume.<\/p>\n

Restores cannot happen in parallel within the same backup set, so again it’s critical that each backup set is kept as small and agile as possible, with a restoration in mind.<\/td>\n<\/tr>\n

Large files<\/td>\n\n
    \n
  1. Put very large files into their own backup set (eg. PST files)<\/li>\n
  2. Schedule sets with large files to run weekly<\/li>\n
  3. Enable delta merging and set the “upload full file after number of previous deltas” to “Unlimited”<\/li>\n
  4. Do not enable an advanced retention policy, this will turn off delta merging and cause major issues with quota sizes<\/li>\n<\/ol>\n<\/td>\n<\/tr>\n
Backup set organisation<\/td>\nDesign the backup sets with restoration in mind: split data logically up into priorities, eg: for smaller sets: \u201cData (current)\u201d, \u201cData (archive)\u201d
\nFor larger sets, split by department, eg: \u201cAccounts (current)\u201d, \u201cAccounts (archive)\u201d.If data is really disorganized then local changes may be required first.<\/p>\n

We cannot stress enough how important it is to keep the backup sets as small as possible and organised with restoration in mind.<\/td>\n<\/tr>\n

Delta merging<\/td>\nIn general, leave delta merging switched off<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
